works good
my only complaint is the small size of the poppet valve. it is only marginally larger than the 1/2" valve that this replaced. I wanted a larger valve with more flow. I don't know why they necked this down to a smaller size.

yuck
poor finish - burrs galore.
poor fit on taper - at least 2-3 thousandths off.
high runout - pounded it in hard to get a best of .005 runout.
suppose it is worth 4 bucks if i can fix it with tool post grinder.
