M21 PRO

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 starsComfort is a 4 of 5While 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.

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

La maquina llego en excelente estado, es liviana, trabaja super bien. Me gusto mucho.

Very powerful didn't have any issues with stalling, the only issue is the grease inside is terrible. doesn't lubricant the gears and makes the machine a little warm after an hour of use but nothing dangerous. Just needed to change the grease and after that is was pretty smooth.

I've been looking for ways to increase my efficiency while detailing lately. Polishing is a time-consuming process, and anything I can do to shorten the amount of time I spend on each car (without compromising on the end result) is very important to me.I decided that even though my 15mm machines work fine, I might try a 21mm polisher. My thought was that if 15mm is faster to cut than the old school 8mm Griot's 6" polisher, 21mm should be even faster. The forums will scare you into thinking that 21mm machines stall all the time and are useless. That just isn't the case.The M21 Pro comes with a 6" backing plate backed up by a 1000w motor. I experienced almost no stalling whatsoever. If you did experience stalling, you could switch over to a 5" backing plate. I am quickly becoming a MaxShine fanboy. These machines are just workhorses. They do their jobs and I've yet to have an issue. Very pleased.

My polisher cam damagedThe hook it pad is damaged

Awesome polisher, feels balanced and solid. The backing plate clearance was a little tight, so I installed the washer that came with it and it works perfectly. I expect this to run for a long time. Really glad I went with the pro model as i almost bought the 900w model becauseI thought it looked better and had better reviews at the time. Much nicer to me in person.

I started reading all the reviews after I purchased the Maxshine 21 Pro. I gotta tell ya I got worried. I just returned a Torx 8mm throw for smelling like it was burning wires inside the very first time I used it. After receiving the Maxshine pro 21 and trying it out on the hood of a heavily oxidized car I was blown away! The Torx polisher stopped spinning as soon as i touched the paint! My brother said Mark a line with a sharpie to see if its not spinning. We did and it wasn't! When we did the same on this maxshine polisher it spun so fast on the paint you couldn't tell there was a marked line on the backing pad! I compounded the hood with outstanding results! Then followed up with a fine cut polish with the maxshine then hand waxed the hood. This car didn't shine this good when it was purchased brand new! Then I did the same on my car and I got even better results. Either these people got a bad polisher or don't know how to use one with the correct chemicals to start with!!! To get great results use great products and I assure you this is one of them!!!
