First Forced Rotation DA
June 27, 2021
This is my first forced rotation DA that I've used in years. I have always steered clear of them from reading comments and other peoples opinions about the user experience. What a big mistake. This machine is incredible for paint correction. Especially on modern cars with lots of curvy body panel. My test subject was a bmw M2 competition. I polished it out last year with the Rupes DA's. The 15mm and the 3 inch random orbit DA. Every single body panel minus the roof on this car is either very curvy or loaded with kink's or even worse a mix of both. I was forced to use the 3" Rupes on over 50% of the car to avoid complete pad stalling. At times the 3" wasn't small enough to keep the pad rotating even on really big sections of the car like where the rear quarter panels meet's the door's. This forced me to have to go over sections 2 or 3 times. This helped push me to consider a gear driven machine. After seeing an Autogeek video on youtube, as well as being a sucker for battery operated machines I decided to give the Flex gear driven DA a try. When I purchased this machine I was under the impression that I would be able to use it for a simple one step or paint cleaner considering its only battery powered. Turns out this was another poor assumption. Again working on the same M2 Competition this machine saved me a few hours of time and the headache of pad stalling. I was able to use 6" Rupes DA pads for the entire car minus the front bumper. Being able to go up on the edge of the pad on a DA machine (while also being effective) was a revolutionary change for me personally. Not one time did I switch over to the 3 inch machine. And not once was I looking for more correction power from this battery operated machine. Speed 4 was all that I needed to plow through the vehicle. And I was able to use the pad in all sorts of creative ways. 3/4 of the pad, half the pad, a quarter of the pad, the outside triangle edge only. It was an excellent experience. Yes the machine does behave much differently than the Rupes long throw DA's, but within 10 minutes of using it I found that instead of putting 100% pressure flat on the pad I was able to favor about 80% pressure on one side of the pad no matter the direction I was moving in (I think on the side of the rotation) and the machine did not walk anywhere on me. If you're like me and have avoided gear driven machines I highly suggest you reconsider. If you care about time this machine can and will effectively replace your entire fleet of large DA's. In over 10 years i've only written 2 or 3 reviews on this website. But I'm so impressed with this setup that I quickly wanted to come here to express my thoughts.
Pros- No cord. Within the first 5 minutes you will be sold on the idea. - Batteries produce consistent power the entire time until they are about 3 minutes to being completely spent - Charger and its excellent display that estimates its time left to charge - Fuel gauge on battery that estimates its charge - Gear driven power that allows you to go up on edge while also applying pressure, effectively allowing you to use a 6" pad is very tight areas that would require a smaller machine on a free spinning DA
Cons- Batteries are expensive, and no matter what anyone says are going to have to be thought of as a consumable wear item. They will need to be eventually replaced and have a life cycle of charges and discharges to them. Compared to a corded machine this setup is going to be a lot more expensive to upkeep over its life cycle. - Cordless was such an excellent experience that I was forced to purchase the Flex 3" machine :)

Great to be Free of Cords!

I purchased this to upgrade from my tried-and-true PC 7424. I wanted to switch to a forced rotation orbital and cordless. This thing is a joy to use! Battery life exceeded my expectations for power and duration. I ordered 2 extra batteries, but I'm thinking the two included with the buffer are sufficient. It has great build quality that feels very solid. I was concerned about the weight with the battery installed, but find that it is very balanced and not fatiguing. My only knock would be the trigger when working on the roof of my car. Its a little cumbersome trying to operate the trigger lock when the buffer is positioned above my shoulders and horizontal. But really, I think this will just take some practice and don't really know of a better way

Flex Gear Driven 8-125
February 5, 2021
This was the replacement for my 5 year old Griots G21 Long Throw. What a difference, you can feel the quality unlike my old Chinese POS buffer. Powers through the worst dull paint, love the gear driven properties. So glad I cut the cord, can go anywhere not restricted by a power cord. Excellent workmanship in this product.
ProsNo cord, lots of power
ConsIf there is one, its the loud charger to charge the batteries.

great for mobile detailers

this flex has amazing power for a cordless polisher. As a mobile detailer this was a great investment and a definite game changer. Highly recommend and will be continuing to purchase flex items.

Worth every penny

This buffer is excellent choice to have if your mobile or don’t like to keep playing around with cords or have a quick section to buff. Has the same power as the 3401. The run time for the batteries is about 30 to 40 minutes which you can get more than half a car buffed before changing batteries. And the charger is the best on the market.
ProsCordless and very well balanced.
ConsThere are none.

Love it

I used it to buff out a test hood and I really enjoyed it. I love not having a cord. Used with some uro-tec pads and some 3d aat rubbing compounding and finishing polish.

Cordless polisher

Feels like it has the power of the 3401. The speed control seems to be in spot where my hand tends to hit it accidentally. May be just me or the size of my hands I'm 5'9" 150-160 lbs. And feels a bit top heavy to me compared to 3401. I may just need some time to get used to. But overall I love it. I can do an average car with half to one battery. I sometimes have to switch to rotary to cut scratches this makes it a breeze to switch bank and forth. No more spaghetti.
