I bought the cheapo Verizon one on Amazon a week ago. It works fine, but like others said, you need to find that sweet spot so it doesn't slide. Last night, mine kept sliding off every 2 hours and waking me up. Full disclaimer: a naked pre sticks a lot better. I have the clear (read: shiny, slippery) skinomi on mine. The only way i can get it to be smoother is if I butter it up.
