I use one on my ip4, used one on my ip3G. I like 'em.. Slightly off-topic, I also use one on my ipad and the other day my cat knocked said ipad off the desk and straight onto our baseboard heater unit. Scratched the hell out of the screen protector. I saw a big gash in the middle of the screen, peeled off the film expecting to see the same gash in the device...nada. Pristine. The screen protector protected😀. I will for sure now never be naked again!!! (except for fun time!!)
