This battery storage case works well and seems to be well made. Fits a good amount of batteries, but keep in mind that if you have odd batteries, like CR123, A23 and button cells, you will have to come up with different ways to store those batteries in this case securely. The only problem that I had was with the battery tester. It worked once, then broke. During assembly, the two halves of the battery tester are put together and a tiny circuit board must be aligned while the two halves are screwed together. The circuit board was misaligned causing a wire to break after one use. I took it apart, soldered the wire, aligned the board and screwed it together. Works properly now. Would by again.
