great! all as in the description I recommend

does a good job especially at the cost.

Wow!!! What quick work this grinder head this does on concrete. It took me a few minutes to get the feel of it and to apply the right amount of pressure to apply. I was able to smooth out my 3 car garage floor perimeter quickly with this as well as leveling out my control joints. I'll be able to use this for concrete countertops as well.

Works well, seems to be a quality grinder head.

Good performance and life, especially for the price.

This thing is amazing. Took paint off a basement floor and barely scuffed the head.
