It is a fairly difficult install. If you get dust underneath you may have to lift up and you risk cracking the protector. Zagg has a lifetime warranty for replacements but you pay shipping ($5.99 or so). I love the feel of the glass..it closely replicates the feel of having no protector on. I also like the clarity provided with protection. My suggestion is you find a Zagg kiosk and pay the install fee. Or go to Best Buy, pay them to install and hope you get a 'geek' that knows how to install properly. If Best buy messes up you can have them replace and try again free of charge until they get it right.
