I am just rating the magazine and not the CPM-E3. 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. It will still work with broken tabs once you close it into the CPM-E3 but the batteries will not be held in place prior to closing. You would have to hold it in your hand and the case will align the batteries in place.

The previous review is not completely correct. The problem is not with the product but with the description what amazon.com put up for the Canon CPM-E3 Battery Magazine. It is a battery magazine for the Canon Compact Battery Pack CP-E3 and not for the camera battery grip. I think the product itself is a great thing, it lets you switch the whole magazine with 8 preloaded batteries instead replacing the batteries in the Canon Compact Battery Pack CP-E3.

The previous reviewer should not judge a product by the incorrect infromation given by a retailer.

They tell you tha this product holds 6AA batteries, and works with the 20D's battery grip, but when I received the item it is for a completely different product and DOES NOT WORK with the 20D's BG-E2 grip. It has the product name of CPM-E3, just as stated...but it accepts 8 AAA batteries and doesn't even come close to working with the BG-E2.

I have had my CPM-E3 8 AA cell battery tray for about 2 years or more now and tonight just noticed one battery retention tab was broken and upon further inspection, two more are ready to break as well. This does not affect the performance of the pack with inserted into the case, but causes an inconvenience as batteries simply fall out if you turn the tray over. I always used the hole on the bottom to push a battery out with my finger--so it must be poor quality plasic--or not enough plastic on these inner tabs. The four on the outside appear to be a bit thicker. I suspect an injection mold issue and Canon should correct this. On the other hand, once inserted in the case, I have no problems. I am not sure I would buy another as I don't shoot enough flash to warrant another tray, and this one still works fine with broken tabs. If the plastic was more robust, I'd give this part 5 stars.

I use the Canon CPM-E3 battery pack with my Canon 580EX Flash. I agree about the battery tabs on the Canon CPM-E3 Magazine... so far I have been lucky and did not have to reload the batteries into the magazine under a stressful situation. I have a secondary magazine with the batteries already loaded. I take "Great Care" when removing or replacing the batteries and I do NOT do it under stressful conditions. Two loaded magazines is more then adequate for my shooting style to date.

If the magazine was constructed with stronger materials I would have given it a 5 star rating. Shame on Canon again with using a flimsy material in thier product line.

"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.

Very good product. My lack of understanding of how to take the batteries out broke one of the plastic guides. So if you buy one of these you are probably replacing one you broke. Use the hole on the back and push the batteries out one at a time. If no you will break it.
