I had read so many good things about this product, and thus feeling confidently informed, I purchased accordingly. After all, like so many, I love my iPad and want to protect it accordingly, so why not spend that little bit more to get a quality product?
Positives first: the product is well packaged, in that you get two protectors, an applicator card (bearing a calendar), plus the sort of cloth familiar to those who wear glasses. I also like the fact that you get an email from the inventor/company CEO thanking you for your purchase, and encouraging you to contact him (I shall be taking him up on his offer). I would certainly concur that there is no loss of touchscreen sensitivity.
And now to the unfortunate bits.
The written instructions are fine, and even somewhat helpful if fanciful, like "apply in a dust-free environment" (I don't have access to a hermetically-sealed lab, although to be fair, they do suggest using a bathroom immediately following a bath or shower, but even this is a bit of a faff). But the diagrams are worse than useless, and even they must be aware of this because the instructions contain a web address for watching a YouTube video, which certainly was an improvement on the diagrams.
I have experience of applying materials like fablon, so I was prepared for smoothing the protector on whilst guarding against air bubbles; after all, if I can manage that on something as big as a wardrobe door, how hard can an iPad be? As it turns out, very, because there is a very crucial difference between backing papers; fablon has a very thin backing, whereas the screen protector's is as thick as the protector itself. This means that it kept springing the edge off, making it very difficult to get started, and once some sort of start had been made, the leading edge of the protector was so far away from the backing that air was constantly getting in. I was alternating smoothing between the card and the cloth, being careful and methodical, yet I never achieved a bubble-free finish.
Whilst the screen certainly remained scratch-free, it seemed to be harder to clean in terms of finger marks. The final straw came when applying a gel case to the iPad, in that it started to lift the protector, thus letting in even more air; already disgruntled with it, this gave me reason enough to fully remove it and take my chances accordingly.
It is a fine concept let down by something as simple as an overly-rigid backing sheet, and unless this was rectified, I would not recommend this product. Read the other reviews, as we can only report on our own experiences.
