Man, I really wish I loved this case as much as you guys. I have been through several of these now and even though I now have one of the good revisions, I still can't use the case because of the clicking feel and sound when I squeeze the case. It happens all the way around the phone too, not just along the sides. Sometimes when I go to press the sleep/wake button the case clicks into place and then I have to press the button again (in other words, the button press doesn't register the first time). It's a shame too because I really like the looks of the case and the fact that it doesn't really add much bulk to the phone at all. I've been using the Incipio NGP from Walmart for the most part (also use my Incase Snap in Smoke from time to time) and that case is totally solid on the phone. Button presses are easy and reliable and there is no looseness or clicking whatsoever. It also does not bubble my PS AG at all (the HD does from time to time). It's a shame that the NGP isn't as thin and light as the HD though, because you really can feel the difference when the case is on the phone.
I went ahead and ordered an SGP Neo Hybrid Matte in Satin Silver too so maybe that will get me closer to the size of the HD without the issues of the HD.
