This particular polisher has stirred some controversy, some people calling it the Rupes killer. Some reviews all around youtube show that it is more powerful than the mkIII to the point that you can polish with an aggressive angle without stalling almost like a rotary. A youtuber also said that he usually uses a rotary to remove pigtails from sanding but for the first time he could take it out with the EX620 wherein the mkIII would take forever to take out. I'm currently debating which polisher I should buy. I'm choosing between Rupes LHR21 Mk3 or the Shinemate EX620 21mm. The shinemate only costs 299 CAD (225 USD) less than half of what Rupes price their polishers and may even perform better. I do detailing for a living and do paint correction a lot. I don't mind spending money on the Rupes but from what I read, the Rupes MkIII has issues with stalling on really tight corners and curves which forces you to pull out another polisher with a smaller pad. Since time is money, I wanted to be able to do everything with just one polisher so doing research on the EX620, some people said you would be able to polish a lot of tight areas where another long throw polisher would just stall simply because the Shinemate has a 1200 Watt motor. I was wondering if anyone on these forums would know anything about it or maybe someone with more experience can look into it as this seems to be a "sleeper" in the polisher market. Would I be better off getting a FLEX 3401 or should I jump into this new product and give it a test myself.
 
Can’t comment on this particular DA but I have two Shinemate polishers.

- Ex 605 5” 12mm
- Ex 603 3” 12mm

Both are excellent and work well for my uses. I haven’t tried anything else though so I can’t really compare.

If you do this for a living and been doing this for some time, what machine have you been using?

I started out with a makita 7-inch rotary for a while when I was working for somebody else's shop. When I started doing this on my own I switched to DA with a Griot's G9 15mm throw it's really good I feel like I can finish out flat panels much faster as I dont have to worry about holograms and can do just one step, the only issue with it is I cant do tight spaces as it stalls a lot. I'm looking to upgrade as my clients have shown interest in paint correction.

The 3401 is a good choice. The newer Flex cordless is another good one. Being forced rotation you can get into curves without stalling.

The g9 has a 9mm throw. G15 maybe?

I tried the Flex 3401 before, it is pretty good with tight areas but I feel like it's not as efficient as long throw polishers in flat surfaces. I might be just doing it wrong, I was using LC orange pad and m105 at that time but I didnt try it out for a long enough time to get comfortable with it. There was a point though that I kept looking at the Rupes Mille but I have never tried it before, and I heard it's a lot more modern when it comes to ergonomics, and overall smoothness than the 3401.

I didn't mention it in this thread but another reason why I'm choosing between the 21mm polishers is because I also detail farm equipment and semi-trucks. I wanted a long throw polisher for large flat surfaces but at the same time do decently in tight areas. That's why I was initially searching for a forced rotation machine with 21mm of throw but I guess no company was able to achieve that, and then I came across the EX620 which might tick all my needs but I feel like it's kinda exaggerated thats why I was wondering if anyone in this forum tried it before.
 
The shinemate 620 has been around for well over 6mths and i have never seen anyone mention it doesn't stall. I suspect any free spinning polisher can stall.

It gets good reviews however. I'm not a professional but i doubt i would get a rupes if i was. Considering the price as you know. You can buy 2 machines, a 5 inch and 3 inch, for the price of one rupes 15mm or 21mm.

3 inch machines are really neat for tighter spots.

My 2 cents..

Exaclty what I did and got and old Griots G15 and a SK mini. All cars have been coming out great! Can’t imagine i’d get better results with a Rupes.

If i were going to buy a high dollar machine it be a Flex gear driven.

Me too. It would be a flex gear driven if i was going to pay that kind of money.
 
Love my cordless Flex CBeast and Pixie. Less so on the Flex Cordless Finisher as it stalls quite a bit on body lines. Love not having to deal with a cord.

Food for thought...

About a year ago I bought a Rupes Mille and while the no-stall characteristic of it, or any gear-driven, is really nice, I have found my old free-spinning MT300 to finish out nicer using the same polish and same pad.

So if speed is your objective, especially in the stall-prone areas, then by all means a gear-driven machine is the winner. But if achieving the absolute best finish is your primary objective stick with the free-spinning DA, and an 8mm one at that.
 
To add another thought to 2black1s's post above....I definitely agree with him but the gears can be taken out of the gear driven Da's to make them free spinning....

So imo buy a gear driven and take the gear out when needed or leave the gear out and put the gear in when needed.
