I bought one of these to go with my Canon outfit and it has been great. It is relatively solid and robust, although, since I take care of equipment, it did not have to be bomb-proof. It holds eight cards securely in numbered sections, all of which are easy to see when the case is open. I always turn used cards a particular way in the case and so can see instantly which are available for use.
It is an ideal companion for any camera case and, at this price, a bargain. There are many more expensive cases on the market but this sensibly-priced case does everything I want.
