I may be the odd-man out here and I'm not final in my opinion, but the initial impressions I had have left me a bit disappointed in the unit. From a base-line standpoint, I am a Flex 3401 guy with lots of Hybrid Force and other Lake Country pads. The CCS and Hexlogic pads from CG"s are the thinnest ones I own. For the record I do not own the Rupes Pads as I really don't want to invest in a whole new set of pads when the ones I have do an awesome job on the Flex.

I know everyone talks about the "beast" Flex and how some feel it gives them a workout. Perhaps for many it does or I'm just plain 100% used to it. I'm not a great writer so where to start? Hopefully, I'll have my son capture some images that will better correspond with what I'm about to share but for now, it's text only.

Ergonomics: Here is the biggest challenge for me. IMO the Flex wins hands down. The most noticeable aspect of it is in the handle and grip areas. The handle of the Flex is contoured nicer and when I grip it near the trigger with my right hand, the grasp does not interfere or touch the trigger in any way. I set it at speed 6, hit the lock button (which operates nicer) and then hold it. On the Flex, the button is a little "clicky" and not as smooth to engage and the trigger throw is long and in the way of my grip. Hard to picture I know but wait until later and then if you have a chance, try them both. Joe mentioned in his video the dial for the speeds. I agree with his point that it rolls almost too easily whereas the Flex "clicks" as is moves making the Mille more easily changed should you bump/rub it. That however isn't something I experienced as it's placed above where my grip is at. It's more just an opportunity to relocate and better place it as a control. It's on the top of the handle whereas the Flex is more well placed on the side where you won't touch it during use unless you intend to and its' slightly recessed making it perfect.

Grip wise, my left hand on the flex is solidly planted on the grip at the end of the unit. It's big so that my entire hand has control of it and when needed can apply presser to it with ease and comfort as it's contoured to my hand. The Rupes is not. It's a much smaller grip and while I have medium sized hands, it is not at all comfortable for me to use my entire hand on it to control. I find myself wanting to grap the actual motor part of the unit and press down. It works but then my hand is stretched to do so and it's not at all contoured thus comfortable.

Another ergonomic point is that the Flex is a shorter unit. That is the distance between the pad and the grip isn't as tall thus with the unit being flatter it's much easier to hold it flat on the surface. Contrast that with the Rupes where it will have more of a tendency to "tip" or wobble. The Flex being flatter also allows me to move it in closer to say a door mirror that is flipped upwards where as the Rupes hits the top of the unit on the mirror. Same with the front grills of vehicles. The flex can get in the lower fascia areas pretty easily.

These two points are by far the biggest disappointment to me.


Control: One of the main points Rupes went after it seems based on the comments here and really why I chose to buy and try it was it's control factor. It absolutely runs smooth and generates a little less (mostly different) type of noise when running. both are fine for me as I tend to wear ear protection but it's a difference. Direction of rotation. Here I think it's 100% personal preference and one where I will go-back and use the Mille with my opposite hands / grip. I actually am fully used to and like the counter rotation of the Flex. Just the same I think what I'm noticiing is what many here who don't use the Flex notice when they first do is that it seems odd. IMO that's what I think people feel when they say the unit "fights them" I'm feeling that same exact "it's fighting me" about the Mille. I do believe it feels that way because it's rotating the opposite way. Makes sense for them as Flex long throw users will not notice it as much. I do and I am going to try and do my best to work with the opposite arms and grip.

Walking....as a continuation of the above IMO they both "walk" about the same. The Mille was not at all any smoother or less "grippy" to me. It felt very much like my Flex, just in the opposite direction. Again, here I think it is due to my being used to one rotation vs the other.


I'm going to stop here with my notes as it's enough for now until I get more time with it but in the end as a unit overall. In summary, it's smooth and totally Rupes like in that respect. My concerns thus far are more with ergonomics. I'll add to this post later as I do have another detail this weekend to work on and worst case, I will sell it to someone locally for a small discount and chalk it up to a lesson learned. Best case, I'll be able to deal with the grip using my opposite hands to control it and perhaps leave it as my back up. For now, the Flex 3401 remains my more comfortable choice but only time will tell. I REALLY want to like the Mille and not just because I put money towards it, but because it does seem to have some strong potential in terms of smoothness and the generation of less noise.
 
I had the opportunity to try out the Mille at Autogeek's Show Car Garage on a couple of projects and I still prefer the Flex 3401. To me the Flex felt smoother.

The head of the Mille sits higher than the head of the Flex, so for me, the Mille has a tendency to "walk" more if you tilt it slightly from a vertical position.

I suppose you can say the Flex has a lower center of gravity and is not as sensitive to "walk" on you.

I tried the Mille with the Mille pads and I felt the Flex was smoother using the Force pads on the Flex.

This is just my experience for what it's worth. Perhaps I'm just used to the Flex and haven't spent enough time with the Mille.
 
A friend of mine had very similar comments about the Mille. He also prefers his 3401 to it. I have yet to get my hands on one, so I appreciate the in depth feedback.

A lot of people say the direction of rotation doesn't matter. I agree that it does. Only unlike you I much prefer the clockwise spin. Some of the issues do sound like they are more about being different. I'm curious, are you left handed? A little ambidextrous I'm guessing if you're considering switching positions with your hands.

I was born right handed and many would say will always be. However after two decades plus of martial arts training when I was younger I am fairly ambidextrous in most things from Sports to writing

I never really bonded with the 3401 which I had and recently sold. Mine heated up like an oven. I am strongly considering the Makita to use only in forced rotation mode. I don't do enough cars anymore to justify the cost of the rupes.

Interesting. I know teaching a left handed to use a lot of our equipment at work was completely different. I never realized that a lot of our equipment was really designed for right handed people until I hired one of my son's friends who Wes a lefty.

My guys were telling me he wasn't picking up how to use the equipment. I went back and watched him for a minute and it was awkward just watching him lol Didn't take long to figure out the problem. I had him reverse which hand was doing what and he did great.

I'll be interested to see what happens when you switch hands. How do you polish? Left hand on the handle at the base??

Yes, left on base with the flex. I may have to switch. I finished up my other basic detail with the flex as it was just going to be too hot too soon to play.

After 35 years of using a rotary the Flex 3401 is far from feeling like a beast.
I definitely enjoy the 3401.
 
Thank you for your review. I have the Flex 3401 and have been using for quite some time. I love it. No reason for me to get another one. As for use, ergonomics, walking and counter clockwise rotation is not a factor for me. I am very used to it. I use ear plugs too and that really helps reduce "fatigue" IMO. The Flex is a beast.

All that being said I am very happy that Rupes has brought their "Forced Rotation" DA to the market as Flex brought out their "Free Float" DA to the market. All this does is BENEFIT the end user! We now have choices in what products we can use to become BETTER at our craft.

REGARDLESS if you go with the Flex or the Rupes, it's a win for us.....PERIOD! Keep on Rocking!
 
The counter clockwise rotation of the 3401 was never an issue for me either.

My complaint was how slow the pad moved at speed 6. I've since altered my product ratios, and can now utilize speeds 4 and 5 to get serious work done.
 
UPDATE:

I found a strong potential buyer for my Mille who should I choose not to keep it has made me a fair offer. That said, I've ordered up some Rupes White and Yellow Pads as he would also take those should I choose to sell. I'm going to give those pads a try even though I'm against and not happy with having two complete systems. I want to do this to give the unit a fair shake and so that as I continue to grow I'm not pinned into just one manufacturer.

If I like it I may just keep it as my son (age 15) who does help me on weekends is not a fan of the Flex and prefers to use an altnerative grip when polishing. This way perhaps I can do the compounding with Purple Wool on the Flex and he can polish with the Mille and the White pads. Something like that.

More updates next week as I'm not planning on doing anything behind a buffer until then.

Thank you for the review and update. I'm still on the fence about the Rupes, but your input (and others in this thread) has me leaning toward sticking with my 3401. My next machine purchase will likely be the Flex XFE 7-12, even if I decide to try the Mille.

Thanks again.

That’s awesome that your son helps you. I hope that time will come when my daughters get a little older. Would love to have that time with them.
 
Great review and input! I a 3401 that spends most of the time in the bag. Every now and then I try it again and just doesn't do it for me like my Duetto and G21 do. But it's a good back up just in case!
