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. ### ⭐⭐⭐⭐⭐ It cant be Beat at this Price! *by on Reviewed in the United States July 10, 2026* Ive been using this machine for 5 years professionally and its absolutely the best bang for the buck! It is a powerful 1000w buffer and smooth polisher. The long throw really helps with the long, deep swirl marks in the paint. Especially on Black! A little more vibration then my other machines, but nothing that effects the quality of the work. I highly recommend this machine. Either for a pro or a DIY you cant go wrong here! 😎 ### ⭐⭐⭐⭐⭐ Great machine *by on Reviewed in the United States October 25, 2025* 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. ## Frequently Bought Together - Maxshine 21mm Throw, 6" Plate M21 Pro Dual Action Polisher - 6-Speed, 5/16”-24 Thread - Auto Detailing Tool for Buffing, Paint Protection, Swirl & Scratch Repair, Glossy Shine, Restoration - TCP Global Polishing and Buffing Pad Cleaning Spur Tool for Revitalizing Polisher Compound Pads and Bonnets - Makita 9237C 7" Polisher, Blue --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sk/products/82322086-maxshine-m21-pro-dual-action-polisher-21mm-long-throw-random](https://www.desertcart.sk/products/82322086-maxshine-m21-pro-dual-action-polisher-21mm-long-throw-random) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-07-24*
