The battery works OK.
I've had it for a few months and took hundreds of pictures, and had no problems with it so far.
It doesn't last as long as the original one, but the difference is not that big.
For the price, i think it's a good deal.
I would buy it again.

I thought I had to purchase the expensive Canon battery to make sure I would get a battery that worked, but took a chance on this battery (exactly as pictured) for about $5 INCLUDING shipping. Came quickly, works fine with Canon charger, and works indistinguishably to the Canon battery.

I bought 2 of these batteries to back up the factory battery. A family member was traveling abroad and availability of recharging was a question. They worked fine and the price is excellent.

The only reason that it didn't get 5 stars is because I haen't had it long enough to determine if it will last a long time. So far it works fine, just like the original cannon battery. It charges good, I didn't time it to see how long but plugged it in, and let it run its course. I bought another kind of replacement as well and cannot tell the difference between it, this one, and the original. Sp it gets two thumbs up!

I was leaving in a few weeks for a cruise, and I almost paid full price for a Canon battery. I needed a back up battery because I was going to be off the ship for 8 hours at a time. I finally decided to buy 3 of these, just in case they were garbage, and if 1 or more could not hold a charge.

To my surprise, they worked just as well as my Canon battery! I've charged them many times since, and they hold a charge just as long as my Canon battery ever did. I was very impressed. I use my camera all the time, and I highly recommend these batteries.

I didn't write my review for about 6 months after I had bought them, because I wanted to give them the true test of time. They passed, and are all still working great to this day!

I hope this helps!

I purchased 2 of these batteries from eforcity and neither one lasted for more than about 10 minutes worth of casual shooting. I purchased other aftermarket NB4L batteries and had a similar result, but I also have purchased other aftermarket batteries and they worked fine. I don't know how to tell which cheap aftermarket batteries will work and which ones won't.

**UPDATE** Eforcity did give me a refund for this product after I left bad feedback, but that doesn't make the batteries any better.

This is a great replacement battery. I've been useing for two months now and keep my camara with me every day. Never fails. I keep one in the camara an one extra all of the time to swap out and re-charge.

Bought this battery to replace the one our camera came with. Its been great and I would buy it again.

Buy two, they're cheap and they'll be in your mail box before you turn away from the computer. At least it seemed that way.

I'm extremely happy with this battery. I've had no problems with it, and it keeps its charge just as well as the Canon battery would. Great price and fast shipping, too.
