Yep or breaks, or gets excessively scratched, installation issues, bubbling problems, they really cover a lot, BUT you will have to pay for shipping (typically $4.95ish?) and on these tempered glass models, they will ask you send the old one back in, in a return package they provide. They also give you also an opportunity to upgrade protectors for another smaller fee if you wish, when you do a claim online.
You will HAVE to go to zagg.com and make sure you have a account with them, and then register your screen protector after you buy it. Then anytime you have a issue, go back to zagg.com, go to your products, select the protector and click on warranty claim.
I will only use Zagg from now on, they are so hassle free and the warranty service is amazing.
