Absolutely the best one!
It's awesome!! It can withstand the most hard play time without leaving a single scratch!
After you put for the first time it is really sticky, but pass your finger on it a couple of time and it get heavenly smoot to slide the stylus.
Little tricky to put for the first time IF you dont know the clear adhesive tape trick. The upper surface sticks to the tape but the lower, the one wich makes contack with the screen, don't!
If it gets really dirt:
use clear tape to remove it;
still holding the screen protector with tape, wash with soap and plenty of water;
dry it with your t-shirt, for example;
and clean all particules left by the shirt on the lower surface with anothe piece of tape;
clean the DS screen then aply the protector still holding by the holy tape;
adjust in the correct position;
hold the protector with your finger and take out the tape you was using to hold the protector;
job done!!
Easier doing them reading.

Fantastic
Simple to apply, practically invisible and unnoticable once in place. Minor scratches on the screen disappeared once the screenguard was applied.
Great great great! Just be sure to completely clean the screens before putting them on.

actually not so good
the thing is the protector itself feels kinda rubbered or sticky what makes the stylus travel not so smooth as it should be and is with other protectors,frankly speaking it's not smooth and comfortable at all, makes the games with slide movements being unplayeble

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.
