### ⭐⭐⭐⭐⭐ 







  
  
    This thing eats concrete
  

*by R***. on Reviewed in Canada on 8 August 2023*

This thing eats concrete but is still very easy to control. I used it to take down about 1/4-1/2" on the edge of a concrete wall to prepare for flooring. The only bad part was all the dust it created.It doesn't kickback and is controllable enough that you could even smooth out a surface in an aesthetic way if you wanted to.

### ⭐⭐⭐ 







  
  
    There are not many diamonds on the wheel!
  

*by A***R on Reviewed in Canada on 25 May 2023*

I used this to smooth out the concrete floor just below where my garage door seal contacts the cement floor. It worked good for the first couple of feet but, after that, it got much slower. I haven't finished the job yet because it took quite an effort to grind the cement. I believe that if it had more diamonds on it that it would work much faster, thereby, making it much easier to use.

### ⭐⭐⭐⭐⭐
