Why not 100%? The casing is top handles, fit and looks really good. But this was mentioned several times here. What a little disappointed me is the fact that despite the name, the phone is not completely protected. Through the shell penetrates the speaker and less dust around a, than in "normal" cover, but the keys still penetrates very fine dust. Here Nokia could calm a little more able to seal. One should now and then remove the cover and the inside a little clean. (This will also get routine when changing;.)) When my cover also the "i" went after a week of "Nokia" lost. Even the cover has now got half a year later little game. So about half a millimeter. But that falls on only when you really rough shoves the phone in the sleeve back and forth. Fell down it is me already. But luckily, actually one of the rubberized corners. So the test has passed the envelope. I've never regretted the purchase! :) And: The yellow is still really yellow! No dirt adheres to it. It has become just a little smoother. Dust hangs just stop at the edge of the screen to, because you have to then just brush a little. (I still have a protective film on it and always taking wipes. Works great. :)
