Purchased from We Sell Bulk here on Amazon and received the item much faster than predicted delivery date - I only say that because there's always a list and it's often difficult to pick which seller is the one to go with. Anyhow, the battery came in original and undamaged Canon packaging (looks just like the images available in product description). I was not about to buy the cheap knockoffs and was worried that the one I ordered would be any different than the one that came with the camera (damaged item or store return). Well, after a couple charges and hundreds of pictures, I can say that this battery is exactly the same as our original. It lasts just as long and charges in the same amount of time. Our camera is fairly new so it was a fair comparison - one battery wasn't all that much older than the other.Email me with questions: mister_mr_d@hotmail.com

The subject is trivial and boring. The writing skill mediocre.I was stuck in Sri Lanka and downloaded it by mistake when learning how to use my new kindle. Decided to take a look.Sorry, perhaps just not my type of book. It is no literature.

Negative

Bought this for a gift and was wondering how it would fit coffee grounds and have room for the filters. I thought maybe the filters were under the lid. Well, it must be only for coffee beans and only a small amount. The filter holder takes up one side of the container and it's not for the kind of rippled filters that we use. It holds ones that are flat. The person we bought it for ended up using it without the lid for a utensil holder.
