Bests & Worsts Reviews from Amazon

I have used these batteries for a couple of weeks now. I can tell no difference from the original Canon batteries other than these last longer. I use 2 batteries at a time (grip), and have snapped ~1,000 shots without the battery bar going down once. These batteries are packaged well and shipped very fast. It took about 2 hours to get to a full charge out of the box. If you are looking for T2i batteries, look no further! **UPDATE** I have had these batteries for a few months and still feel the same way as mentioned above. I have been using the batteries without the grip (1 battery at a time) and seems to get about 20-30% more shots than the stock Canon battery. Recharge time is about 2-3 hours from dead. Spend your savings on lenses, not "Canon" branded batteries.
