It seems integrious
Appears to be sturdily built. I am happy with it so far.

Great tool for metal workers.
Very good die grinder, good power and has a decent weight to it. I’ve put decent amount of pressure on it and doesn’t slow down. Great tool for fabricators and welders.

Trash, but good value
This thing is a piece of trash, but you don't get much for $60 these days. Four stars because it's a decent value.
