I agree with this. I bought this recently, largely after seeing M. Saban Smith using one on youtube. It's really nice to be able to take ~20 seconds to freshen up the bowl gouge.
I'm sure I'll end up with a ProEdge or something one day, but I already had a bench grinder, and all the sharpening systems plus jigs are eye-wateringly expensive.
