Summary: Getting the job done

Comment: My original RAZR battery -- at a full charge -- was dying after a 20-minute conversation. I don't know if this replacement matches a factory battery in terms of how long a charge lasts, but it's made me forget that I had a battery problem and I can get a lot more mileage out of my phone now. With a motorola battery at $30-35, you can't go wrong here.

Comment: Took this battery with me on a trip as a back up battery for my Canon powershot 1100IS camera. This battery lasted me good 200+ pictures.

Summary: I love these batteries!

Comment: I have a Canon supershot camera that I carry in my purse and the expensive CANON brand battery never held a charge. These batteries are sooo reasonable and they hold a charge for a LONG time.I recomend them!I carry an extra one in my purse!!

Comment: For the price the battery is a good backup for Canon made battery. Would buy this battery again.

Summary: great cheap battery replacement

Comment: I used two of these batteries to supplement my original Canon battery on a two week camping trip. I charged them properly before using them and they are indistinguishable, if not better, than the original Canon battery.

Reading some of the reviews it seems that about 1/4 of the users are pretty unhappy with this product. Assuming that they do everything right it may be that the production standards are not all that high, and one in four batteries is defective. Given the low price I think even then it's still a good deal: buy three of them, check them out, send them back if they don't work. At the time I bought my batteries that would have still saved me about twenty bucks, including the postage to ship the bad ones back.
