Review: Excellent Backup Machine for Professional User - It is important to note that I used this machine professionally on a daily basis for one solid month. My main dual action polisher is a Rupes 21 Mark III. Great machine, but unfortunately it was down for a warranty claim and I needed a backup. Since the MaxShine machines intrigued me, I decided to buy a 21 Pro to compare to my Rupes and to have as a backup when it returned from warranty service. I used it for a solid month and can say the following: Ergonomics are great, actually. I like the feel of the machine in my hands. The handle is thick and nicely angled. The head is palm sized for my larger hands and has a solid rubber grip that really looks nice too. The tool feels more compact than it is, if that makes sense. Its proportions and weight distribution are excellent. 5 of 5 stars Comfort is a 4 of 5 While it doesn't vibrate badly, it is not as smooth as the Rupes. I would describe the feel as more of a rumble than a sharp vibration. I have used it for spot work as well as hours long compounding and polishing jobs with no pain or fatigue. If I had never used this type of machine I likely would not have even made mention of this. I have added the "washer mod" underneath the backing plate so that there is no contact between the shroud and plate, but the plate still doesn't spin as freely as I would expect. With the machine off I spin the pad by hand and it stops quicker than other machines. Is this a lower quality bearing or something else? So far it has not made any odd noises, does not over heat, or give any indication of premature failure so this may be a non-issue. Don't confuse this with stalling. I have no complaints about its abilities. It seems to be an excellent value for the money spent. It costs less than half the Rupes and does the same things. The differences for me are the rumble feeling especially at higher RPM and my question about the bearing. Whether you are a professional looking for a less expensive backup machine (or even primary, who knows) or you are a hobbyist this is a great machine that does serious work in fine fashion.
Review: Great machine - With a 21mm throw this unit is my go to for heavy scratch removal, but can be used to polish and wax too. Minimal vibration and fits well into your hands.

### ⭐⭐⭐⭐⭐ Move aside Rupes...
*by A***. on October 21, 2018*

This is my second 21mm polisher I bought it as a back up to my torq 22D. Ok so this polisher is great. Compared to the 22d its shorter in length, its trigger is spot on with the variable speed dial. Its very powerful and the 1000 watt motor delivers a lot to the pad. It feels like quality and its vibration is average. I see no flaws with it yet. Although the supplied plate did hit the shroud so I replaced it with a 22d 6 inch plate and now it spins freely. I would definitely recommend it. So now I have my 22d with a 5 inch and the m21 pro with a 6 inch..will be snagging a 12mm I think...2 month update- all I can say is..perfection! This 21mm delivers on every level. Performs better than the torque 22d..worth every penny of $210
