Input: Consider Input: 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

Output: Positive

Input: Consider Input: This book should have been written more as a novel than a how to. This book goes into story like dimensions and there are others better written on the subject.

Output: Negative

Input: Consider Input: 30 minutes into it and I'm bored out of my mind. Woe is me "hero", terrible acting, yes it's an action movie, so let's see some action, don't try to wow me with dialog. If you're looking for something to grab your attention, this isn't it. Thankfully I didn't have to pay for the movie.
Output: Negative
