Ya its not the best, but i would say its neutral. Not a pro or con. I rarely have to struggle putting it on, occasionaly the 1st thread is a pain, but after that its smooth as most. Taking it off is easy as can be.
We have to realize that Chinese QC isnt the best so something on yours could be perfect and crap on mine and vice versa.
yea true it would be better if it had a cap like the SX that used a coin is thicker so can have better threading than the thin chrome one it has. But then some would complain you have to keep a nickle handy to change bats
