The case is relatively well finished and fits perfectly on the phone. It replaces the back cover of the phone and snaps in the same way. The card holder has little interest since Samsung recommends not to place any card with a magnetic strip, also for a credit card is best avoided. In use, you get used to the case especially since the front flap can be folded over the back of the unit. By cons, if you own a car holder the case does not facilitate its insertion into a support or even completely prevented. In this case, it will remove the case in order to fix it, which is a shame.
