I have both the front and rear protection on my Ipad Air and find that this screen saver works extremely well. I had no issues in applying it to the device and no residual bubbles or problems with it after putting it on. My wife can hardly tell the difference from before and after application. I am so confident in the screen saver, I often carry my device without the smart cover/case I have as I find it gets in the way.
I've had this protector on for about 1 week now. Does the job. Ended up drying clear and clarity is great. I used the wet application. Only thing I don't love is the feel. I miss the feeling of slick glass. However, this was a pretty cheap way to protect my pad. Needed to as it has a few scratches due to tumbles it has taken. If you want the feel of glass, this isn't it.
