Installing the two cover pieces was easy and almost instantaneous. There are two tabs you need to pull, one removes a plastic slip so the "sticky" side is exposed and can be applied to each of the two phone LCD screens. The second tab you remove after applying the sticky side.Well, the second tab I couldn't remove easily ... ended up gunking up the scratch-resistant surface (but not the LCD screen itself). After scratching for a few minutes, the gunk went away. It was a good proof-of-concept test ... the screen doesn't have one scratch on it after I was done. 4 stars ... 5 if the second tab could be removed easier.Side Note: This worked on a V3a MotoRazr just fine.
