For the price, this is a great set.
The cases look good, feel good on your hand and fit easily onto the phone. The only problem is the cut out space for the USB charger. The charger hole does not allow the micro USB lead to fit in the way its meant to. So once connected, if you move the phone in any way, the charging lead will fall out. Apart from the black case. If you look at the picture of the cases close up. The black case is slighly different. (You can tell from the camera hole space - there is an extra cut out for the small holes above and below the camera lense, compared to the other cases). This case seems to have been manufactured better dimensionally as the space for the charging lead allows it to be plugged in with out any problems.
My advice, would be to look for the better cut mesh cases ie the ones with the extra cut out holes above and below the camera as these seem to be manufactured better. However I've not seen any of these better cut cases in colours other than black.
