This is by far the best screen protector I've used for curved screens. There are a few steps involved but it's not complicated and the instructions are very clear. Unlike other screen protectors (like the $50 one that Verizon sold and installed for me) these do not pop off and do not reduce touch sensitivity.
As a side note customer service at Mobilefun was very helpful when the USPS lost the first package. I contacted them and they sent out another which was delivered in a couple of days at no cost.
