I've worn cheap holytrainer clones before, the regular and nano sized ones. The nano-size worked better for me most of the time since my dick is pretty small when it's flaccid, but I was able to fill the entirety of the regular-size holytrainer when aroused and my dick was getting as large as the cage permitted. The ring chafes and irritates the skin under my balls after a while and I think the fully-enclosed nature of it is unsanitary and I started worrying about that and the general low-quality of these Chinese knockoffs enough that I stopped wearing them.
This is probably just a "me" thing, but I always got aroused when putting on a cage, which made it difficult to fit into. I had to distract myself, try to put it on while watching a youtube video and being flaccid, because I can't get it on with a boner.

if I ever wore a chastity cage again, I'd go for an open design like this.
