We recently replaced our open-box buy Philips 42" LCD TV with a Panasonic Viera 42" after the control board in our old one finally died. The new TV had a mirror reflective glass covering the screen, and we have French doors with full glass panes in our living room. The reflections were so bad that I installed curtains over the doors the next day to try and make the TV watchable during daylight hours.This screen protector, which I didn't buy for protection, does indeed cut the glare and reflections dramatically. It doesn't eliminate them completely, but it reduces spot reflections to a very diffuse reflected glow (think of a light bulb seen in a mirror, versus a soft glowing area).Installation took about 5 minutes. The instructions were simple, alignment was easy, and I was relieved to see that there's an L-shaped overhang to hook over the top of the TV. It fit our 42" Panasonic Viera perfectly in the visible region. The supplied Velcro strips are black, and hardly visible even in daylight. I haven't noticed any detraction from the visual quality of the screen with the protector in front of it ... it's really very optically clear.To the person that rated it a one without buying it, but only because they didn't see their issue answered, please consider this your answer and remove your ridiculous review. That's not how reviews work. It's a great product. A little on the pricey side, and the shipping box is nearly as large as a 42" TV, though there's no way around that I suppose.My way of applying the protector to the TV was to attach the velcro strips to the TV bezel edges, firmly pressing on each one for 30 seconds (bracing from the back a little). Then I remove the other side of the adhesive covering and quickly placed the screen protector into position. The instructions say it's a two person job, but it was easily done by myself. It's very light.
