I only know of best buy and so far have been to 3 area stores
Store 1 installs and says lines and bubbles go away after 2 days. I wait and bubbles go, but still have buncha lines
Store 2 installs another and it has defects... I ask the guy to examine before his next install and he had 4 more on the shelf... everyone had ripples or lines in it
Store 3.... they all had defects... sure they will warranty etc.. but where the heck can I buy one and have it installed without defects?
Also the 1st to admit, I could not install one if you paid me... 2 left thumbs
