Do you trust Boeing batteries? (I rode one of the last 787 Dreamliner flight in January) What about the Sony
cell phone batteries that exploded in some guys pants? In 2006, recalls came from virtually every major laptop manufacturer—Apple, HP, Toshiba, Lenovo, Dell, and others. Apple alone yanked 1.8 million iBook and PowerBook battery packs from market.
Canon battery = battery + mark up. Wasabi = battery + no mark up.
I don't know about all y'all, but I think I trust Canon a bit more than some random company named after a spicy condiment to keep my hands and face from blowing up....
