I must say that i have had the most experience with this grinder over all the others. Where I work during the day bought one 4-5 years ago for a couple of reasons. 1) being the safety factor. A open bench grinder is very dangerous for working with a small piece of tungsten. 2) We wanted to have the portability of a hand held grinder. 3) we wanted to get the most out of our tungsten buy grinding down to a point where you can't use it no more.
The only reason I gave this a 4 and not a 5 star rating is the fact that if you ball up the tip of your tungsten to big is will not fit through the collect.
When I'm personally ready to buy a grinder this will be the one.
