This product was a complete disappointment. As my tests showed, the power output was lackluster and couldn't handle even moderate jobs. The build quality was shoddy and not up to standard for an industrial and scientific tool. In terms of pros, it was easy to OPERATE, but that was overshadowed by the cons .Its safe to say I won't be purchasing from this brand again..
Pros
Efficient grinding due to a powerful pneumatic motor
Cons
Limited mobility due to the need for an air compressor to power the grinder
