I have a small home biz repairing HTC phones. Buying Digitizers from Ebay has not been too bad but it does happen once in a while. I'm talking maybe 2% I would say that its rather amazing that any work what with how some are shipped. *No padding. I just found this site and am glad there are other people who hate throwing away great stuff like the HTC phones.
BTW That gap where you get 1/4 of screwieness is how I see these fail. Don't give up. *Or if you do send me the broken phone! I'm always looking for more of these to fix.
