I have had more bad experiences with them than good, so I can see your point. If I hadn't randomly picked one that turned out (so far) to be good, I would have agreed 100%. I can't say it was anything other than luck that I found this one I've got, but yeah...it's scary out there. You really have to know what you're going to accept from them, which is hard when you're in a diminished or vulnerable state.
