Inside and out, the case has solid sounding protection for mobile use. The lined with soft microfiber pouch to protect your investment, while the stable outer shell case is likely to absorb the occasional shock; at least that is my impression. The proof of the pudding I previously did not dare, for my 3DS is too grown very fond.
While the 3DS easily fits into your pocket without case, it is with this case clearly too thick. This I give all those along the way who are looking for an explicit thin protective sleeve. The wireless receiver and the StreetPass function affects the case of course not.
As a single, truly single, I still quite disturbing criticism I have to complain that the case for all models listed except the DSi XL is clearly advised too large. Although you (whatever) DS can attach two Gummizugbändern reasonably determined in case, it can easily happen that a DS.lite / i or 3DS during transport including back and herrutscht. I would have liked much better when, really just a 3DS would place in a case that adorns the 3DS logo, then you could save the somewhat cumbersome attachment to the elastic also.
