Input: Consider Input: My daughter loves her blocks. She will get them all out and look at each one until she finds her favorite. She likes to shake them and see what each one does. These are cute little blocks that have hours of imaginative playtime inside. They also have blunt corners, so no sharp edges like wood blocks for the safety of smaller children. The fact that they have the letters of the alphabet and a corresponding object inside makes them a great learning tool even for older tots. We have really enjoyed these and recommend them to our friends.

Output: Positive

Input: Consider Input: I'm sure these are great socks, but I was slightly disappointed when I thought I was getting 3 pairs for the price listed...my package arrived and there was only one pair for the stated price. I feel like the image with 3 socks was deceptive and "false advertising", as it states nowhere else how many pairs are sold for the stated price. Hope I enjoy the socks, but thought I'd warn everyone else before they buy these and expect more than what you'll receive.

Output: Negative

Input: Consider Input: Vista has been out for 4 years, I'm up to Windows 7, and they still haven't released a driver update for this scanner!This is what's called planned obsolescence, where they intentionally make something not work so that you have to buy the new version. There's no reason or excuse for Visioneer not to release an update.This was the last scanner I'll ever buy from Visioneer. How can I have any confidence that they won't do the same thing with their new scanners when I upgrade computers again?
Output: Negative
