Well, I finally received my black Nokia OK cover from Allack today (ordered it a month ago), and it's far from being OK. The material is really cheap and flimsy. And most importantly, the damn thing DOES NOT EVEN FIT properly. I can (kind of) get the front cover in place, but it's far from a snug fit, and the back cover just wont fit at all.
A word of warning to those of you thinking of getting one.
Cheers
