Ownd,
When you wrap, include some of the head, try to wrap a little past the ridge, and you'll have to wrap a little tighter than you think. It still cannot handle too much stretch, use the lightest springs and try to get them to compress halfway, that's about the extent of force I've been able to handle before slippage problems start. The good thing is, once you get it set, you can leave it on a lot longer than any other device, as long as you want really. I've gone to sleep with it on a few times, although it's not recommended, but I've worn it during the day for 6 to 8 hours in a row without circulation issues.
