For about 20 euros, including shipping, it's worth the maximum! It goes without saying that it requires a mask, protective glasses, and gloves because it produces a lot of dust and there is a high chance of causing an accident with the concrete pieces

Flawless. I made a groove in a cement floor (2m length, 2cm depth) in order for water to drain away, and when I finished, the disc had no slightest damage.

Excellent product! I measured a 25 square meter terrace covered in mold and residue from previous insulation for the application of new insulation, and it not only had no difficulty at all, but it removed everything and is still intact!!! For around 20 euros including shipping, it is definitely worth the maximum!

Of course, it requires a mask, protective glasses, and gloves because it produces a lot of dust and there is a high chance of accidents due to the concrete pieces

For the money, there is no reason to think that "I wasted my money" more than honest for the money... Take into consideration the 125mm diameter on the classic small angle grinder, it will tire the operator a little more.

It's perfect! And the best part is that because I hate my neighbor, this lifts infinite dust and ruins her balconies, and I'm happy about it
