These were the first screen protector that I've ever applied that worked first go. I bought these for my Panasonic G3 and they fit perfectly. No bubbles, no fuss, no stress, no swearing! They have great instructions and extra tools to make it easy to apply. I have six of them for not much cash so I don't care if they only last a couple of months. I have at least a years worth of screen covers. I'm overall very pleased!
