Battery works well. - The camera runs and doesn t run out of juice in 5 minutes. I m a happy customer.
Garbage - Complete waste of money - I bought two of these and NEITHER of them holds a charge for more than a few hours EVEN WHEN NOT USED. DEFINITELY stick to the OEM batteries.
Only equivalent in shape and color - Battery is rated at 900mah as opposed to OEM Canon NB-4L (760mah). You should theoretically be able to operate the camera for longer periods. However with the same camera (Canon SD300) settings and flash operation, the OEM Canon lasts considerably longer for a given full charge. Good emergency battery for the price, (you can t use AA s in an Elph) but stick with the OEM for performance.
As good as Canon s $60 battery for one-third the price - I have purchased two of these for when I have more shooting to do, and they work great. I haven t measured the number of shots I can get between this and the Canon battery, but they seem equivalent in how long they last.
