Hi, I have a T10, have had it about 6months. Not had any problems with it, other than pellets clipping the end of the silencer (caused by a rubber washer on the end of the barrel, was fine when this was removed). Mine was a bit fussy with which pellets it liked, but once I found some it does like, it can put all 10 pellets in a group about the size of a 5p coin at about 30-35yds. With the silencer I got with it (cant remember make) it really is quite quiet. Also quite loud without it. Only thing about it as has been said in previous post, is that the saftey is a bit awkward, and i find when I put it on I do have to move the bolt handle up slightly.
