I own two of these cases (one black, one white). First off, the cases definitely look the part and when brand new, FEEL very solid and well-manufactured...in the beginning.
As mentioned by several others, an annoying gripe is that it needs to be opened for charging, the white one gets mucky (unsurprisingly) quickly and the lip can be a bit tight and difficult to open and close when new, but it does soon loosen up.
Generally though, the functionality of the product is good. Dropped it a few times and managed to get away with only a scuff to the leather. The screen remains scratch-free and it keeps dust out very well.
The main problem however, is the build quality >2months. The leather starts peeling off from the edges/lip after a couple of months and with the black one, it survived for about 5-months before the leather came off from the plastic completely at the lip and the plastic ended up snapping off.
I'm currently 2.5 months into using the white one and signs of the peeling have started at the top corner edges & the lip.
I'll be replacing it soon though as it's become an unsightly stained grey atm (not the fault of the case), but I'm hesitant about getting another CP-572 because at this price, I expect it to last for more than 5 months....
