In short, this sticker puts in the inner side of you DSi which might avoid the handhold console from dust and dirt. What a super rocket the manufacturer take that they can release such a weird thing without any omen the minute DSi reaches another sale summit. The first impression makes us feel good while receiving the sample, however, thing begins to turn to the opposite side when our fellow try to team up it to DSi. Frankly speaking, he is a conscientious boy and we confirmed that he’d read the manual word by word before starting his work. After 25 mins he finally accomplished the mission but that is not what we want to see. Anyway, we are not very much impressed with this one, not easy to use and the hand feeling is really rough. The most horrible thing is that you can hardly escape from the the air bubbles. Look at our poor guy, he now gets a headache. How about you?
