Zagg is amazing! You don't need a receipt or anything. If you haven't already registered, just go on and register it with an approximate date of when you purchased it, then request a replacement. They send you a replacement and an envelope to send back the old one. You pay only for shipping. If you do not send back the old screen protector, they say that they will charge you full price for it, but you have plenty of time to get it done. If you had the original installed at Best Buy, they will install the replacement for free. I just did this a month ago or so. In addition, I wanted to replace the scratched up screen for my son's Nabi. I saw that I hadn't registered it and couldn't find it on the site. I emailed them to inquire about it and they told me it had been discontinued. Since they offer a full lifetime warranty and couldn't fullfill it, they simply sent me a gift card for the retail value of the screen protector... without registering it and without a receipt. (I guess they saw that I have many other screen protectors registered already. LOL) I used that toward a new one for my new iPad Air 2 and it was during their buy one get one free promotion so I grabbed one for the ipad mini that I got my hubby for Christmas. Definitely happy with the customer service and will continue to purchase their products.
