The first month or so I owned this, it protected my phone 24/7. The credit card pockets have the right size for a couple of cards.
The covers is clicked on the back of the phone and sits very tight. It doesn't move or falls off easily.
The only downside is the extra thickness it adds to the phone. It takes a lot of space in my pocket. Which is the reason why I changed back to my old flipcover, which replaces the original backcover.
So if you would like to keep your original backcover, needs the space for the credit cards and doesn't mind the extra thickness, then is it the cover for you.
