Review on Maxshine M21 Pro Aio Scratch &Amp by Richard Deng

It is important to note that I used this machine professionally every day for a month. My primary dual action polisher is the Rupes 21 Mark III. Great car but unfortunately it was out of warranty and needed a backup. Intrigued by the MaxShine machines I decided to buy the 21 Pro to compare against my Rupes and use as a backup when it comes back out of warranty. I've been using it for a whole month and I can say the following: the ergonomics are really great. I like the feel of the car in my hands. The handle is thick and beautifully curved. The head is palm sized for my large hands and has a solid rubber grip that also looks very nice. The tool seems more compact than it is, if that makes sense. Its proportions and weight distribution are excellent. 5 out of 5 stars. Comfort - 4 out of 5 points. While it doesn't vibrate a lot, it's not as smooth as the Rupes. I would describe the feeling as a rumble rather than a sharp vibration. I've used it for spot work as well as many hours of blending and buffing without pain or fatigue. If I had never used this type of machine I probably wouldn't have even mentioned it. I added a "wash mod" under the base plate so there is no contact between the cover and the plate, but the plate still doesn't spin as freely as I expected. When the machine is off, I rotate the block by hand and it stops faster than other machines. Is it an inferior bearing or something else? so that shouldn't be a problem. Don't confuse this with stopping. I have no complaints about his abilities. It seems excellent value for money. It costs less than half the rupees and performs the same functions. The differences for me are the rumble feeling, especially at higher revs, and my bearing issue. Whether you're a pro looking for a less expensive backup machine (or even a main machine, who knows) or a hobbyist, this is a great machine that does some serious work in subtle mods.
