A:Answer Best Buy will install the Zagg shield for you, but they usually charge for that service. It is under $10.00 if you decide to go that route. They are easy enough to install as long as you are in a clean environment. If Best Buy installs it and gets any debris under the shield, they will remove and put on a different one. If you do it yourself and get debris under the shield, you would have to purchase another one or live with the imperfection.
