being someone who's used the Canon version of this battery pack, i have to say that this product is very, very good. i shot a 4 hour event with this battery pack, and one 580EXII, and got over 500 shots with it, at varying ISOs, with absolutely no problem, no slowdown, and no having to change batteries! 500 shots! crazy!

to be fair, the canon product is much more 'solid' feeling, and will probably last longer, but for the price you really can't go wrong.

differences:
-the canon battery pack holds 8 batteries, and this one holds 6.
-unless i'm wrong, the battery pack doesn't 'kick in' until the batteries in the battery pack become necessary. on the canon product, the small red light goes on every time you fire the flash. with this one, the light doesn't come on until the battery pack becomes necessary for the recycle. i don't know if this is supposed to happen, but it does, and that's fine with me.

i like the belt clip with the velcro pouch, and how much lighter this one is than the canon one. remember, that's because it has 2 less batteries. for half the price of the canon one, i really, really recommend this product. hope this helps. [...]

I thought to myself, why spend $150 for a Canon flash power pack when I can get this one for $50. I'll tell you why. "If you buy something on sale that ends up breaking after one use, you haven't saved a dime". In fact, if you end buying that $150 product anyway, you've actually wasted $50.

That was my experience with this battery pack. As noted by the other reviews, this pack "feels cheap", like if you dropped it the wrong way, it would crack. I thought to myself, if perhaps I babied it, I could probably get a couple years of use out of it. Boy was I wrong. At this point, I would have been satisfied with a couple of months use. After one photo session, a wedding, this pack would no longer latch with batteries in it. It latches fine without batteries, but for some reason the pack doesn't operate without batteries. LOL.

If you still choose to buy this product, understand that you are buying a disposable product, and you may dispose of if sooner than you think. If you're a professional or a serious amateur, you know that manufacturers like Canon and Nikon make a ton of money marking up their products a lot more than they should; but you take solace in the fact that you'll never have to buy that product again. This is not that type of product. If you buy this product, you are trying to get lucky, and unfortunately my luck wasn't so good.

Why give it 2 stars instead of 1, you ask? I try to give credit where credit is due. When this pack was working, it did exactly what it was supposed to do and enabled me to capture the shots I needed to get. If you only photograph weddings outdoors on sunny days in the summer, a battery pack for your flash is non-essential, but if you shoot indoors and occasionally use a flash, you need a flash battery pack to keep up with the moments that would otherwise be missed or turn out underexposed.

I ordered two of these battery packs. Within 3 shoots, one of them stopped working entirely. I sent it back for an exchange and within that time, the other started working intermittently. When I received the new one, it wouldn't even come on!!

I ended up sending both packs back for a full refund. They cost me many shots that cannot be duplicated and I can't afford that in my business. They are cheap battery packs and that's how they work...cheaply! Look elsewhere for battery packs that can relied upon!!
