1. These protective seals have stickers on both back (protection of the protective seal) and front (the real protective seal). It's almost impossible to get them off without permanent markings!

2. Very soft and scratchable. Not durable at all.

I recommend buying better protective seal (e.g. by HORI).

new review
okay, I originally wrote a crappy review for this product but I just realized today it was human error and not the filters themselves which made them crappy. I'd put the darn things on backwards. To be honest, I partly blame the instructions. They lable the filters "top" and "bottom" screen protectors, clear enough. Then they label each probetor "front" and "back". I had assumed the "front" was the side facing the player and the "back" was the side facing into the ds. Well, when I put them on this way, the bottom screen protector got scratched up within minutes of playing. It got so bad that little particles started to flake off of the bottom. It finally occured to me that maybe I'd put them on backwards. I've just flipped them, keeping the top on top and the bottom on bottom, and presto, a thousand times better. I was going to order the Hori ones but now I'm going to give this brand another chance and order a new set. I have no idea if they were labled backwards or if that's the way they were supposed to be labeled so if you buy them, remember one side will feel smoother than the other. The slightly tackier side is the one that touches your ds. Good luck.

Too soft
It doesn't take a lot of pressure to scratch this up. I just bought this and after twenty minutes of playing a game, the bottom screen protector was full of noticable scratches. I also had a lot of bubbles, even though I put it on in the bathroom after running a hot shower to get rid of the dust. I guess there's just no way to get a real dust free environment. My star rating is based mostly on the scratches though and not the bubbles which I blame myself for. Once I have the ds turned on, I don't see the bubbles or scratches as much unless the screen goes dark but it's still disappointing to see how easily it gets scratched. I am going to buy the Hori screen protectors now and see how they compare.

Different protectors, same problems
I don't know about the three users below me, but the complains in this product are no different from HORI's. Once the dust gets into the seals, you can't remove them, and the dusts are extremely noticable when in a lighted room. Overall, it was an unsatisfying way to spend 4 dollars.

Then again, the product IS four dollars, so anyone buying this won't lose much dough, and the end result could be way different from mine's. Still, I can't ignore the irks I have with it (for all I know, though, I could be create those irk), so all I can do is recommend this product WITH EXTREME CARE.

Not bad
I have some queries about this product that I hope you don'tmind answering.........
1) Does it have covers for both screens?
2) Does the Top screen coover reduce glare like the Hori one?
3) How does the it affect the friction/sensitivity of the touch screen?
4) Does it produce any rainbow affects?
5) Hows the durability?
