Great machine it ok not bad price ok not to bad fair had one issue with blade but issue was fix and good

Im a contractor, I install flooring for a living. Ive been installing floors and trim for 10 years. Im 28. It came to me with some runout. Fatness wise/in and out movement. And it was hopping around and kinda hard to control accurately. I think it was from being dropped during shipping, the shipping strap was broken and it had a big paint chip and dent in the handle metal. Cracked paint, but not cracked weld. Or it could just be that way since its so cheap. I didnt expect total perfection at 900 bucks. Either way I ended up shimming the mounting plate with aluminum cans. I had to do two bolts out of four to make it run true. Tried just shimming one bolt up, but couldn't get enough adjustment. But shimming two of the four bolts made it true within a 64th of an inch or probably less. You can barely feel any in and out movement now. Visually it looks to be perfect, but I can still feel a tiny wobble. But its running extremely smoothly now. Also the cheap attachments aren't flat, so they need to break in for 50 to 100 feet before they fully even out between them all. Then it gets extremely smooth to run. The blue grinding bits that they include are just the right Bond to cut into relatively hard concrete. No glazing issues. I have freeze thaw cycles here and it has no problems with hard concrete. Overall im very happy and impressed at the price point. They just need to ship with the mounting wheel detached so it cant bottom out on the motor shaft anymore during shipping. Them it'll bottom out on the dust shroud instead. Which is way preferable. I think a lot of people would get it and assume its just running that way because its cheap, when it might just need an adjustment. Saves a lot of headache. You can pretty accurately shim it with some pieces of aluminum can with a hole cut in the center to slide the bolts through. I think it took four shims on one bolt and three on the other and now it's pretty close to flat. Make sure to get the brushless one, its lower power than the bigger one, but the big one has a less efficient brushed motor. So you're going to be blowing Breakers for no extra power. And more overheating issues. I'm trying to include some photos of a 3X3 area that I ground in about 5 minutes but for some reason I can't include those here so. I ground about 3:30 seconds of an inch off of a 3X3 area in about 5 minutes and that was with a bunch of repositioning because it was such a small awkward space. So this machine should be able to do quite a bit of grinding in a small amount of time if you actually have room to maneuver it. The stoop that I ground was super rough and wavy and it is dead flat now.

I'm excited to use my new grinder but it came damaged. The strap that's used to hold the grinder to the pallet broke in transit causing the grinder to bang around in the pallet box. I tried uploading pictures but am not able to. I will contact customer support.

I received the package about a month ago and only recently opened it to discover some damage to the box. The control knob is difficult to turn, requiring pliers, and the motor shell has some dents. I would appreciate it if you could arrange a replacement. I hope you will consider my request, as I need this for my new business.

Good machine, works like it's supposed to. Motor does stop with upward pressure. Great product for the price!

The machine is well built and easy to dial in for making a nice smooth level concrete surface. Dust collection works well when you have sufficient air flow (my 5 gallon shop vac and vortex thing on a 5 gallon bucket setup worked well enough, when the shop vac filter was clean). My only complaint is that due to the machine's light weight, it really needs the aggressive diamond wheels that came with it to work efficiently on some surfaces (I was removing a tar-based waterproofing membrane from ancient concrete). Unfortunately, Vevor doesn't offer exact replacements and finding 7/8" arbor grinding wheels is not as easy at it might sound. I was finally able to find an aggressive enough wheel from Blue Rock, but it was too tall for the dust collector to touch the floor (problem solved with tape) and the arbor clearance on their 7/8" arbor made for quite an interference fit. If finding aggressive grinding wheels for this machine was easier (hint, hint Vevor), I'd give this five stars. I certainly wouldn't have been able to get through my whole house concrete floor job without it.

Bought to grind thinset down after chipping up tile. It does the job but is slower than a 7in grinder with a dustless attachment and it leaves behind a lot of fine dust even with the vacuum attachment. Also trips a 20amp breaker easily if you put to much pressure on it to grind

Purchased this grinder to do my own garage. Delivery failed; FedEx would not deliver it because the shipping container was destroyed. Had to pick up at the local Fedex warehouse. There were parts missing from the shipment (2 of the abrasive pads) that are supposed to come with it. Contacted Vevor and got a canned response. Still no resolution. I did try to grind concrete with it and it's not very stable due to it's light weight. Between the broken machine, poor (none) customer support and poor quality of cut, I wouldn't bother purchasing this unit a all. You can rent a commercial grinder with HEPA dust collector for less money and get a proper grind. I'm trying to send the unit back to them, however, they have stonewalled me and they just won't take the unit back. Highly recommend NOT buying this product unless you like to be hassled.

Very good but breakers always tripping. If the breakers is on its own it will be ok don't plugs nothing else. Buy a portable generator for safety

Hohe Vibration ( rtatelt) und die backen sind nach 3 Stunden schleifen fertig. Motor zu schwach beim auflegen ohne rad
