Amazon shipped a generic replacement, labeled "Power2000", "ACD-763", "for Canon BP-827", with the address of a no-name company in New York. There is no official Canon logo anywhere! Instead it says "Manufacturers [sic] names are trademarks of their respective companies ... for reference purposes only ... do not constitute any form of endorsement ..."!! The barcode on the back is taped over with an external sticker that carries a different UPC code and says "Canon BP-827". It's obviously a fake. Very, very shady indeed. If I wanted a generic, I'd know where to buy it. Here, I wanted brand, and I got a knockoff represented as brand (it says "by Canon", and there is a picture with a Canon logo on the battery in the item description!), at more or less brand price. (The knockoffs are ~$50, not ~$120.) Take your pick what to think. I thought those fly-by-night outfits out of Brooklyn operated like this. Needless to say, it's going back. Simply unbelievable! Grrrr.
