I have one. it does work , its kinda loud.. Choosing the right media is the biggest challenge, some of the rock blends leave a nasty film on aluminum parts ..
We used to just stick the stock out a little further and use a double 45* tool, (90* included angle), to chamfer the part-off area pre part-off to chamfer both the back of the part and the start of the new part simultaneously. Then part-off. You are using bar stock? Then, move the stock up to the stock stop to set length for the next part, and you already have a chamfer on the front edge. The bar feeders we used had spring fingers. HTH
I'm using a Rebel 17 with 10# of stainless steel pins, water and a few drops of Dawn. It really works well on anything!
