So far I'm in agreement... I gave up cause I can't get the f'n thing to stay on. It'll stay on like 2 minutes then the rod slips out of at least one end of the tubing, sometimes two. If I go to sleep with it, everything will be separated by the time I wake up. I've tried everything... gluing it, etc. Only thing else I can think to do is melt the tubing with a lighter and hope it bonds to the metal, but then when cleaning it, it would become an issues. So yeah scratch that... nothing I can do... f* this thing.
Why not just make the f'n things have holes then put some elastic stuff in it so it contours to a stretch or something. I dunno, but being as it is, the tubing that's supposed to keep it on sucks.
