Maxshine ShineMaster M15 15mm/900W Dual Action/DA Polisher

My wife and I own a custom detail shop and ordered the MaxShine 15.I've been using Rupes for awhile now but gave up on them after losing 2 Rupes 15 units in under 3 years.First impression out the box....First thing you'll notice is the nice bag the DA comes in.A bit surprised to see the included bag, a plus.Extra brushes included too.This was a nice add on their part to give us the brushes, just in case.The machineFirst impression on first use...Was working on a faded Toyota when the DA was delivered.Was using my Flex 3401 at that time.I took it to my cart and put a MaxShine Polishing pad on the unit.The MaxShine 15 felt really good in my hands right away.When I hit the switch it was so smooth, more so than my Rupes 15., was a bit surprised by that being the Rupes cost far more.To my likings....Well madeDoesn't bog down like the Mark IICooler running padsThe backing plate is really nice.It not only has holes under the backing plate but also on the side which releases the hot air keeping my pads cooler.MaxShine is made by MaxShine which is always a good thing.Because of that they give you a lifetime warranty even on a less expensive model.Two small things I didn't like but still gave it 5 StarsThe power cord could be better but I can change it out myself.The DA doesn't have slow starts it has fast start but I adapted to it quickly.Will order 2 more for our staff

This was my second machine. The first one Amazon sent to me used - even had a completed warranty card inside but everything else was gone. I returned it immediately. This one was exactly as ordered and it works exceptionally well. I'd highly recommend it to anyone wanting a quality DA and a reasonable price. I did a hood correction and it was quite, smooth and powerful. I don't think you could ask for a better polisher for the price. Maxshine you have a real winner here!! Very happy to have this in my detailing cabinet. Going to do a YouTube video soon and I'll post the link when completed.

Bought mine February 2019. I use it a lot and still going strong! Have probably done 100 cars with it, so far. It can stall out on edgy panels, but it is a DA not a rotary. Trust me, if you had to pick one polisher, and not be paying up the azz, this is perfect.

Now, I'm not a paint correction specialist by any means, but I do a fair number of enhancements and one step corrections. I do some 2 step corrections from time to time but i try to stay away from those for now.I started my detailing business with the Harbor Freight 6" DA polisher that everyone in the world has used at one time or another. It vibrates way too much, is very loud and doesn't do a very good job at cutting, and makes your hands hurt for hours after using it. It has it's place in detailing, but it's not really a full car piece of equipment.in comes the Max shine 15 mm DA (called the Shine Master now - same polisher new name) and it's my first long throw polisher. I was very eager to use it.Upon opening the box, there was a fairly nice carrying bag inside, a D handle and screws, extra brushes, a washer for backing plate modification, and a hex key. The 5 " backing plate was already installed and tight from the factory, so no need to do that. Also, the backing plate spins freely while the unit is off. Basically, this was ready to go straight out of the box. And there was a smaller bag to carry all your spare parts as well.I was very eager to test it out, and since I can't operate now due to the COVID-19 pandemic, I tested it out on my wife's metallic grey Saturn with very heavy oxidation, scratches, halos, you name it, it's on the car. I didn't prep the panel correctly (I didn't even wash it), just did a rinse-less wash on a test section with nothing else. I taped off my test section. Unfortunately, I didn't have any 5" foam pads (i thought i ordered a 6 " backing plate but oh well), so I put a 6" orange cutting pad on and used 3D One 400 (one step correction). Using the standard Cris-cross method, I attempted to remove the scratches and swirls.With only a few drops, I was able to remove SOME of the scratches. I'd say the orange pad removed about 50% of the scratches. I then switched to a polish pad to finish it off. There were still noticeable scratches, so I upped my game to a 5" Uro 50-50 pad. Primed the pad, did standard 2 pass at about 1 inch per second. Well, that did it. The clear coat was just harder than I thought. Then I followed up again with a polishing pad and I was actually able to see the metal flakes pop! That's exactly what I was hoping for, so I was very pleased at how easy it was to remove the deeper scratches with this unit. And even while applying a decent amount of pressure, it didn't stall one single time.Pros:WAAAAAY better than HF 6" da polisher.Very easy to controlSoft startTrigger speed controllockable triggerVery low vibrationClick confirmation speed dialeasy to access speed dial when usingCons:I don't have any because this is my first long throw DA polisher. However, compared to the HF one, this is like night and day.BUT!!!!!! the grease inside the Maxshine gearbox is horrible. Just don't use their grease. It's cheap and offers little protection of the polisher.Do your maintenance immediately prior to first use. Remove the bad grease that came with the unit. It's crap and it will not help you. In my case, their cheap grease (silicone) actually made the machine vibrate and was fairly loud. So, instead I got some Valvoline high heat, red lithium, marine grease and packed the gear box completely. It made a huge difference in how well the machine worked. It was less noisy, less vibrations, smoother operating and didn't get hot at all.I have literally zero experience with a long throw DA, but I really like this polisher, even knowing that there are better polishers out there. However, I feel this is an adequate polisher for my needs. It's not heavy, it fits my hands very well, it doesn't vibrate too much and my hands were not numb after using it (unlike the HF DA).I would recommend purchase of this unit based upon my initial impressions.Unfortunately, my State is under a stay-at-home order and I'm not allowed to operate my detailing company because of that. So, I don't know how long it's going to be before I can reopen. I mention this because I'd like to give updated feedback, but it's going to be awhile before I can do that.Again, I think this is a nice starter DA long throw polisher. It's not very expensive for a long throw, and it's made of very high quality materials.Not only would I recommend this for purchase, but I WOULD buy another one if I need one. Maybe the 21mm one instead once I get used to the increased cut from the 15mm one.Edit: July 14, 2020 - I have now used the polisher several times. It feels good and hasn't had one single problem. It does get some vibration but that's only on huge body panels like the hood because the support is less in those areas which I assume are prone to vibrate with any type of polisher.I'm very pleased with my purchase. It was not very difficult to learn how to use it either. I was a little intimidated as I'd never used a long throw. But, this was very easy to learn. I still recommend this as a good polisher. It just works and it's not uncomfortable or has made my hands gotten numb. Now, if you had to use this every day, all day long, I'm not sure. I don't do that amount of detailing, nor do I want to lol. This seems more like a solid and well made unit for entry level users.
