Great
After comparing this thing to ones local gamestop had, these one, my application of protectors was not perfect one, but i was happy (two air bublles because i had remove and reapply the protectors, and use my nail take protector out what folded them little)

One thing is, get some clear tape (it doesn't NEED to be clear but it is best) For these reasons:
1) This is tool you use remove the protectors, even the instructions "say" so.
2) You can use tape on dusty parts of the protector bottom (what goes againts screen) to remove dust.

Also, if you have SMALL scrathes (kind what cannot be seen if you aren't in sun) These protectors HIDE them from bottom screen, but if you have BIG scratches that make screen color rainbowy in some angles, those won't hide...

In the end, from any other screen protector, THESE are the best, no doubt that!

Excellent! The Best of the Best.
This product is indeed the best of its kind! People say "oh no, it's so complicated to put it on", blah blah blah, but it's easy. All you have to do is BE CAREFUL and TAKE YOUR TIME. Actually, once you have the position right, it literally secures itself into place, with NO air bubbles! I have a PDA screen protector/filter and I have to push it in manually, leaving bubbles all over the place, unlike the HORI protector. Once it's done and overwith, you'll be glad you did. I don't even notice it and it even makes everything amazingly clearer! Definately a great buy.

Really tricky and therefore not good!
I had many problems to get the protection sheets on my Nintendo DS and in the end I had to put one of them into the trash can. This is really disappointing because I have other protection sheets for my iPod and cell phone where something like hadn't happened.

Great.
It is quite easy to put these on provided your screen is clean, but getting the screens clean isn't easy, that's the problem. Anyway, if you got them installed properly you will not even notice they are there, which is brilliant.

Great!
The way they look, the way they are to be applied, these protectors are just great! @neurokwarg: if these protectors weren't slightly smaller than the screens, it would hardly be possible to apply them correctly. Five stars for me!
