I ordered the
Gecko slimfit cover for mine. It expensive, but I quite liked their Deluxe cover on my Glo HD that I picked up from a third party seller for dirt cheap so it seemed like a good idea to support them directly. The cover is quite nice (and in itself waterproof!). It's very tight and secure - so much so that after wrestling the device out of it once, I'm apprehensive about repeating the performance
It adds about 114 g to the weight of the H2O2 and feels much more durable than my previous experiences with kwmobile and other sellers of covers where the closure magnets are visible. Sleep-wake function works well and the front cover doesn't bend or move so much that putting the it in a bag with yhe reader would feel in any way risky. The material feels kind of funny to the tough, but after a while, the rubbery honey-comb-patterned inside cover in particular is kind of nice when folded back. Not as nice as the back of the naked Kobo, but good enough that I shouldn't be sorry if I'm really stuck with it full-time now.
