unique offerings but quality could be better. perhaps I expect too much for that design. I don't know. nothing is perfect but for $45 I expected a little better. tiny gaps etc. I do not know if that is to be expected from something hand turned. it is not terrible but for the price I expected perfection. perhaps I expected too much. I have several and they all have very minor flaws. this is down to nitpicking though. unless you expect absolutely perfect I would still recommend them. no one else offers 8mm and 22mm anyways afaik.
