## Customer Reviews

### ⭐ Don't buy
*by J***R on February 24, 2026*

Was too hard to handle while using Bad design

### ⭐⭐ Not worth the money
*by T***N on May 22, 2026*

Really rough to handle. I got better use with my 4inch angle grinder.

### ⭐⭐⭐⭐ Price/value very acceptable compared to alternate choices
*by S***N on March 7, 2026*

The machine performed as I expected. Not easy to guide or steer with the single handle, but you could attach another makeshift outboard handle easily enough to help guide it. I used it to do a light scarify on a 735 sq. ft floor. It worked OK for that. There is a speed adjustment atop the machine where you can slow it down, so it's not so crazy to control. You can use it without the extension handle by gripping the machine directly, and it's easy to control in that configuration. I was on uncoated concrete, old and new surface. Surprisingly, it didn't make clouds of dust on the highest speed. I did not attach a vacuum, but a port is provided and easy to connect to. Putting it together was straightforward and easy, and they provide the basic tools to do so. Considering the price/value I think this unit is fine for a small job, considering large professional machines are really heavy, not a one man job, and typically thousands of dollars to purchase. This is good for a job like a single or two car garage, or a like sized patio. I noticed very little wear on the four diamond discs that came already mounted on the machine. I didn't use the other polishing discs or wire buffing discs that were also included, but they might come in handy for your project. All in all, not bad. I'll probably sell it, since I no longer need it, and come out cheaper than a rental.
