Pros : Easy to Use
Frees your hands for work
Cons : Slight time delay between pressing and activation
Other Thoughts : I can't believe it took me decades to figure out I needed to buy one of these. This makes grinding glass so much easier and hastle free. I just walk up to the grinder with glass in hand, step on the pedal as I walk up, and by the time the glass hits to work surface it's at full RPM. Highly recommend!
