I've personally had no problems with Spigen. I've ordered several times and not one issue. Irish Rose definitely got unlucky because I've also called them about a few issues and they have sent me out new SP's without any problems, although YMMV, not all experiences may be the same. Maybe they are all a bunch of jerks and I got lucky. Having said that, Power Support is probably one of, if not, the best company out there to get protectors from. I actually just ordered from them. I haven't tried out their back protectors yet but if they are anything like the front, than they will be amazing.
