In Vancouver - with a few beginner queries

First off - does anyone else here call Vancouver, Canada home? Second up, a few beginner questions. I’ve been fascinated by this concept since last summer. I picked up two units: the CB-6000 and the BirdLocked. Over the last six months, I’ve worn one or the other for about 24 to 48 hours at a time, maybe a dozen times total. Each has its downsides. After chatting with my wife, we’re looking to weave it more deeply into our daily lives over the coming months and see how things progress. The CB-6000 actually broke while sitting in its pouch, so that one is out for now. Given what seems like low build quality, I don’t intend to buy a replacement. As for the BirdLocked, it also has some notable issues. It tends to slide down during wear, leaving the base of my penis exposed. With just a bit of lube (or even moisturizer), my cock can easily slip back out, and once that happens, it pretty much slides off completely. My question is — isn’t this an issue for any device? Next up: I’m not quite ready to splurge on a custom-made piece yet, but I want something better than the BirdLocked or CB models. Has anyone tried the Holy Trainer Next Generation? Any thoughts? Feedback would be great! Best wishes.
