I got these for my blackberry and ipod touch. They work fine and are easy to cut and apply. I was apprehensive at first with the number of so so reviews on Amazon, but what is a better alternative? Every screen protector gets so so reviews and some are much more expensive. When these wear out it is no big deal to slap another one on because they are cheap. Do not expect to have perfect application. The trick, IMO, is to start in one corner and carefully smooth out bubbles as you lay the plastic down. If you try and smooth them out from the center, it just doesn't seem to work as well and you scratch the surface in the process. The scratches do seem to happen, but I think that it is hardly noticeable at all once you turn the device on. It is noticeable if you are looking at the reflection off of the screen at a 45 degree angle. These are great and when I run out, I will buy more. BTW you can get two applications from one sheet and they last for a couple of months.
