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

Ordered two and tested them out: one had a bad pump but the return was easy.These airbeds are super cheap and great. Everyone who has slept on them says they are extremely comfortable. They hold the air well. I recommend them very highly

Ex Output:
Positive


Ex Input:
Incredibly uninteresting film with characters you don't care about, a nondescript and swelling music score that all but drowns out whatever mumbled diagloue there is, and a computer-game feel to the aerial sequences. Really tedious. If you want to watch a movie about aviators in World War I, watch "The Dawn Patrol" with Errol Flynn and David Niven.

Ex Output:

Negative
