Here we have some screen protectors, a couple of clear stickers designed to cover both screens on the Nintendo 3DS and protect them from dust and dirt. But do they actually work? Well, as mentioned in the review title I found the end results to be mixed.
First I removed the stickers from the packaging. Being careful to only handle the stickers by the edges, I first worked on the lower touch screen. I was able to carefully fit it into place without making it look like a slanted picture frame. After smoothing out the air bubbles with a flat object (I'd suggest using an old credit card or something along those lines) the result was perfect. No dust, no dirt, no bubbles, and my stylus worked perfectly fine on the screen afterwards. Brilliant.
Then I moved onto the top display screen, hoping to get the same outcome. Sadly it wasn't to be. I had an incredibly hard time matching the sticker up with the edges of the screen exactly, although after a few attempts I got it very close. But despite wiping the screen with a microfibre cloth beforehand, I found a lot of dust still managed to get trapped underneath the sticker; and when I smoothed out the bubbles a lot of dirt built up around the edges, and some of it still remained stuck on the screen after I'd tried to wipe it off. It looked like a mess.
So a 3-Star score from me for these screen protectors. Are they worth buying for your 3DS? Yes, but only for the bottom screen.
