"The tabs that hold the batteries are VERY, VERY weak and will snap off very easily; so be very gentle when inserting and removing batteries."I ditto this. For thirty-two bucks, Cannon should make a more stable magazine. Those using these magazines are probably event photographers who use one or more of these gadgets on a regular basis. I'm very careful with my equipment, but it didn't take much for the little tabs to snap off.
