Best DA orbital I've ever used
June 4, 2016
This is my second unit. My first lasted almost 8 years. This time around I opted for the professional with the 25' cord.
Gear driven. It delivers as much power as you need to get the job done.

Simply the best dual action polisher!
May 9, 2016
I love this polisher! This is the only dual action polisher that will power through defects like a rotary but much safer than a rotary. The ergonomics, power, quality & ease of use makes this my favorite polisher I own. Get the 4" Lake Country backing plate along with Lake Country 5" & 6.5" Hybrid pads & then you'll have everything you'll ever need for that show car finish!
Simply the best! Fit, finish, power & quality!

Built like a tank!
February 5, 2016
So, I've been using my Flex 3401 for 4 years now - probably on my 350th+ full detail. I've run over it with several cars, I've dropped it countless times, even sprayed it good with a aerosol can of electrical cleaner to get some "gunk" out of the vents. As I picked it up to place it on my cart to let the cleaner evaporate, I managed to hit the power button and a spark from the brushes ignited the whole thing. It had crazy flames coming out of it for probably 5 seconds before I managed to extinguish it. That was a year ago. Still going like new - swapped probably 10 backing plates, and brushes four or five times. I got the 21mm and 15mm Rupes, but keep coming back to my sweet "keep on spinnin'!" :)
- Built like a Tiger tank - Forced rotation, just keeps on spinning! - No issue working -all- areas, even sharp bends, kinks and all curved panels
- On huge flat panels a large throw DA like Rupes 21 can be more effective

An excellent polisher that easy to use with all the power needed to get outstanding results. My Makita works well also but I get less splatter and can work safer using the Flex. An orange pad with the Pinnacle compounds get my cars ready for a couple coats of Fuzion wax for absolutely WOW FACTOR results for late spring till late fall and then Klasse Sealant for durability for the winter months.
1. Safer to use 2. Less splatter using the orbital 3. Love the longer 25 ft. cord on the HD Model 4.Smooth and quiet operation
Pricey but it's well built.

Love My Flex 3401
May 1, 2015
I had been using a Meguiar's G110V2 and it works well but after using my 3401 for the first time I will give my G110V2 to my son. It took a little getting used to, about half a doors worth of polishing, so I was controlling it instead of the other way around. But once I was used to it I found I could work faster to achieve the same results.
Well made Plenty of Power

February 19, 2015
I used a PC for a couple years, wasn't real happy with the power after a couple months. This machine has plenty of power and is a very well built machine.It definitely is a time saver. The forced rotation is the way to go!!!
Power, forced rotation, time saving, if I ever decide to sell it I can recover most of my money.

Nice Polisher
November 2, 2014
Works great for all task never misses a beat direct drive keeps thing rolling alon.
Nice for doing anything you want to do Direct drive is the way to go. Don't buy cheap polishers buy the best your wasting your money on the cheap junk.
No storage bag comes with the unit sadly after spending good money for the unit. I believe the company outta send me one. I would recommend the product tho but make them throw in a free bag.

Does better job faster than PC 7424
October 14, 2014
Used the Porter Cable unit for 7-8 years and was perfectly happy until friend told me about Flex. I used same orange pad and same Menzerna 106FF and got fabulous results quicker. Flex is stronger unit and therefore not as easy to control as PC so glad I had the experience of the PC unit, not that you couldn't learn the Flex in one or two outings.
Ease of results, well built.
Pay attention and don't lose control.

Flex 3401 DA Orbital Polisher
August 30, 2014
My experience with car bodywork upkeep is very limited. With some research and advice I selected this excellent machine and have used it with Meguiars products to get my car back looking the way it should. I own a black 2014 Cayenne which was abused by some totally unprofessional body shop workers when it went in for a small dent repair. They had used a rotary machine of some sort with some nasty polish and the 3 month old car looked like it was 10 years old, even paint spray on some panels on the opposite side of the car to the dented back panel. The Flex DA with Meguiars Ultimate Compound on Lake Country pads made easy work getting all noticeable swirls out (adopting techniques illustrated by Mike Philllips) and overspray off. Now the car looks new again, I am a very satisfied customer.
It's so good you may want to play with it too much !.

Fantastic polisher. Put that blue foam pad on and polished those scratches right out of there. The 8mm throw is just right for this machine. This polisher and a 3 inch rupes is all I need to make me happy.
Fast removal of scratches.

Gear driven head, best quality

If you are looking for the best in an orbital buffer, this should be on your short list. Everything from the cord, head, body, are top notch. Action is smooth, it's quiet, and doesn't get hot even on low settings. Very nice product

Great Polisher
June 1, 2014
Used on my new ashen grey Camario with a Meguire's soft buff foam polishing pad with Meguire's 205 polish and Chemical Guy's 5.5 in. hex logic finishing pad with NXT Tech wax 2.0. First I used Meguire's 205, one medium fast pass using my Flex 3401 then I used hex logic finishing pad with my Flex 3401. I did not let the car lot to detail it. I wanted to do it myself. Though my paint was smooth, I had water spots that did not want to come off. I researched all the products I bought. These were the best products to remove it safely. All spots are gone, polished to shine and waxed for protection. Keep in mind my Flex 3401's speed was no higher then 3. My Flex Dual Action Orbital Polisher 3401 is a great product and highly recommended. Autogeek shipped my Flex 3401 quickly and is a great business to work with. They included the Mike Phillips' book and dvd and it was a very helpful guide with great info.
Easy to use if you watch the dvd and read the book. Of course, if you're experienced it should be an amazing product for you (Flex DA 3401 polisher)

Was hesitant but glad I made the purchase
May 18, 2014
The reviews were stellar but I already had a Porter Cable orbiter. Also, the price....$350!!!!! That's a lot of cash. Long story short, I pulled the trigger and made the purchase, The Flex is night and day compared to the PC. It worked wonders on my 2007 black Mustang. The direct drive mechanism is what sets this unit apart in my opinion. If you're on the fence like me, jump off and make the purchase!

Good middle of the road polishing action
May 4, 2014
I own and operate a body shop and bought this polisher to use as a second step polisher after the heavy cut is done by the rotary polisher. As for using it as a buffing tool to remover orange peel or after dirt nibbling you can forget this polisher I cannot do it in a timely fashion. But i had decent results using it as a swirl remover or a glaze polisher. If you plan on using this as your only polisher if you are a professional your making a bad decision, but if you want to add a tool to your polishing line up it is a good middle of the road polisher for light polishing or maintaince polishing. I just hope it holds out because you have to run the speed very high to get a good result in a timely manner. Very happy with purchasing from auto geek. Well package and very fast shipping at the right prices and stock all accessories for this machine.

Best DA machine out there!!
April 27, 2014
Having worked for a while with the rotary machine, I didn't expect this one to be so good!!!! it is very powerful and it really works!!! actually I can forget about rotary machines now. It is extremely easy to work on wet sanding and to work on scratches and it really feels sturdy.
Lightweight, sturdy, fast, easy on hands, perfect for wet sanding, durable, reliable, affordable.

Great tool
April 16, 2014
I have been using a porter cable d.a. polisher until I got the flex 3401. I realize what I have been missing. Easy to use, and great results. The forced rotation gives you an advantage over other d.a. polishers. Better results in less time.

The definitive DA Polisher
February 21, 2014
Not long after this Flex 3401 arrived I realized to my horror that this electric appliance would probably outlive me, and I am still years from retirement. It works so fast, that the waxing of the car is kind of an anti-climax. To justify it I think you have to be younger than I am and have at least two good cars that you like to take care of (i.e. wax at least three times a year each). My thinking was: Do I want to pay $130 for a tool worth $60 (but still very effective) made in a factory in China, or do I want to pay $350 for a $350 machine? I went this way. I can see most people going the other. This is unquestionably a pro tool.
Like bringing a machine gun to a bar fight. Durable. Reliable. Powerful. If you use this as intended, your cars will look wonderful. Saves time. This means in practice that your car stays waxed all the time. Your probably get all your money and then some back at trade-in time.
Expensive--but not overpriced. More tool than most amateurs need.

Flex XC3401
August 4, 2013
EASY to use machine even for a novice. I have a good deal of common sense but let me stress I am no super duper natural at all things mechanical (in fact I'm normally intimidated by such things). That said, I started at low speeds to get used to how this machine handles and within 10 minutes was buffing at speeds 4 to 5 as the machine has a scale of 1 to 6. Turns out the machine was the easiest to learn. It's the polishes and how quickly they break down as well as how much to use that was the learning curve for me. Please note there is no damage done even while learning. You simply go over the area again until it's right. DO NOT BE AFRAID TO BUY THIS MACHINE...it's is awesome and my first time out made my car look like incredible using Menzerna products which are user friendly to a novice since they have a long work time before they breakdown and dry out. I thought I was taking a chance by buying the Flex over the PC as I thought it might be too powerful. It is powerful in that the machine is capable of serious correction but it is so safe to use. For uneven surfaces, slow it down and tilt the pad as needed. If you're the type of person who likes quality and would rather buy once rather than replace a cheaper item down the line then just buy this machine and skip the other garbage out there. You will not regret your purchase.

Just finished detailing my Montego Blue 325i today. I used it with Meguairs NXT machine polish. This was my first time using a machine polisher and I am thrilled with the result. All small scuffs and scratches have disappeared and not a single hologram. I highly agree with your review of this product. HiFi Man, Ireland.

A wonderful buffer
June 11, 2012
I have used this buffer for just about 2 years and I am simply amazed at the results I achieve using the Flex XC3401. I previously used as 10" buffer which was much more work and the results were substandard. I actually look forward to polishing my cars. Thanks FLEX for such a great product.

Simply The Best
April 17, 2012
Best DA polisher on the planet. Makes the PC, Meg, and Griots look and feel like Harbor Freight tools. First thing you notice is the quality and fit and finish. It's made in Germany so I expect high quality. Second, you'll notice it's a million times smoother than other da polishers. Lasty, it corrects very quickly. Anyone telling you a Griots and match the 3401 is crazy. I still keep my other DA for spreading wax.

It lives up to the hype
November 12, 2011
Well as the ex-coach of the Az Cardinals would say "It is what we thought it was!"..meaning, its awesome. WHY? Lets start with how smooth it runs. Not having to worry about if its going to keep spinning or not like a standard DA. This thing keeps moving which is great but is ESPECIALLY helpful when doing things like...along a tape line or body line where you want to get that last 1/2" or so where the swirls sometimes like to hide. If you tilt a DA on its edge to get extra pressure to the edge of the pad, most times it quits spinning. Not the flex. I've experienced MUCH nicer 'trimming' results with this baby. Tilt it, put the pressure on the edge...let it do the correcting, wipe away your polish and enjoy the COMPLETELY swirl free results. Another things ive been please with is, for ME at least, on factory clears...it works great with the Meguiars D300 compound and cutting disc. I have not experienced any hazing from it and its great to have something that is so easy to use like D300 on a machine that has that extra edge to it. The ONLY thing id say be careful of is...don't touch the cast iron head on this thing after you've run it a few passes..it gets hot. I got a couple little stingers the first time i used it just because i was use to grabbing that part when i go to clean my pad on other DA's...but now i've totally gotten use to just holding it upside down by the main body...no problems. Awesome machine and if you can get it i say go for it. You'll never want to part with it.

A time saver and money maker!
November 11, 2011
To me time is money. If I can do a job faster, then I make more money. For years I've been using the Porter Cable 7424 and it has worked out fine. I decided to take a gamble and pay three times as much as a PC for this FLEX. It paid for itself almost immediately!! With this particular tool I have found that I gain at least 30% efficiency in my detailing. With a Porter Cable you have to stop the machine, change the speed, and then start it up again when you go over a thin area like a leading edge or a hood scoop. With the XC3401's variable speed trigger I just slow it down when I need to and then go back to full throttle when it is safe. All without having to turn off the machine or change my speed settings manually! There is also the fact that the entire movement is gear driven. There is no stopping the forced rotation of this polisher. That also gains you some power and efficiency. It won't fix anything the Porter Cable won't fix, but it will do it in less time, and that is definitely worth it. Anytime you can buy a tool which can turn a 3 hour job into a 2 hour job, you have to get it!

Used it for three years now, with incredible results and no problems. Easy to handle, effective on all paint finishes, and extremely well-made. I expect it to last a long time. I am not a commercial detailer, but a very finicky amateur. I usually use the Flex for initial clearning, followed by second with Klasse All-in-One, then use Klasse final coat, applied by hand. Then I follow up with PS-21, by hand. The Flex random pattern removes swirls and does not produce them at all, used as directed. After having used the cheaper brands, I consider the Flex a revelation. The 6.5 hook and loop Lake Country pads are also a great product, and the Flex makes optimal use of them. The Flex is great for the larger jobs, and its durability allows one to use it without worry of its overheating on the challenging jobs.

A wonder to behold
May 30, 2011
Took advantage of a discount offered & decided it was time to upgrade from a PC to the Flex I had heard so much about. I had spent about 2 yrs with the pc & was getting GOOD results but nothing spectacular for the time spent - thought polishing just might not be my thing. In comes the Flex & the difference was obvious from the second I cranked her up. I used a 3 step polishing process & just knocked it outta the park. Actually, I've realized the OK results weren't a result of my ability, I just didn't have the right tool. Jeweling, hmmmm, wonder if I can master that !

The perfect DA
May 17, 2011
The Flex 3401 is a fantastic polisher, I can't believe that I waited this long to get one. Now that I own one I have several important points to share. Being a direct drive DA this polisher has serious power. It is impossible to stop the rotation, so using 6.5'' pads on curves and vertical panels is no problem whatsoever. Most importantly the vibrations with this polisher are a fraction of the typical DA which was very important to me. I used to have my hands go numb after only an hour of polishing, now I can finish out an entire car with no problems (4-6 hours). It is expensive, but I wish I started off with this DA. It trains you how to correctly polish (hold the pad exactly flat) and it has epic correction power. I can not recommend this polisher enough.

Flex XC 3401
October 26, 2010
I have had for a couple of years now and the it has never disappointed me. It does not free spin so it has enough friction to work even deep scratches (use on my truck after running through the woods in norther Michigan) and yet I have never come close to a bulls eye. Plenty of power and fineness. Only complaint is that I got it with the Flex Bag which blew out an upper inside seem with in a couple months of receipt (only had the unit 4 bottles of Mirror Glaze (Side Pockets) and the CCS Pads I bought with it). Have used it with Mirror Glaze and Pinnacle wax, excellent result with all. Cars, trucks, and boats again excellent results all around. I always use it with the CCS Pads. If you have 1/2 the results that I have seen you will be glad you purchased it, just don't spend money for the Flex Bag...
