Title: Stay with name brand
Review: I purchased these batteries with the Opteka battery grip for my Canon XTi. After only a couple of recharges my camera started locking-up. I first thought my camera was the problem but after lots of troubleshooting with a Canon rep realized it was the batteries. The Camera and grip work fine with Canon batteries. Better to avoid cheap knock-offs. You really get what you pay for with these batteries.
