I got one for my LG Optimus V and there was a long scratch on the adhesive side and the cover itself was way small. It was about a full 1/8th inch smaller than the screen all the way around. I contacted Zagg and to get a replacement they required that I ship the screen protector (box and everything) back to them on my dime, then put a credit card on file with them so they could use it to ship me a replacement. Well....I bought the screen protector for $5 (used a $10 gift card that I got for free when I bought my phone) and it just didn't seem like a good deal for me to spend over $5 more to get a replacement. Besides, I didn't feel comfy putting my CC on file with a company that I had never dealt with before. So, I tossed it and got an Mbat brand screen protector and its been perfect. No reduction in touch screen sensitivity, glare or orange peel texture and its as slick as the bare screen.
Zagg, if a rep is reading this, just send someone a replacement for free. Why make people jump through hoops??? Afterall, your not replacing a phone, just a $15 screen protector.
