I've never had problems and have Zagg on my Droid and my wife's Alias. I had one on my Omnia before Droid. The only problem on that one was the corners started to peel... that was probably due to me not waiting long enough to let the shield "cure". I've had no issues with peeling on my Droid full body... but iI did let it set a lot longer before using it after applying. Probably 3-4 hours.
I also had a problem with a corner piece tearing on my first shield on my Omnia. Zagg replaced it, no questions asked. I only had to pay a shipping fee and return my old shield.
