Example Input: This was my first purchase of a vibrator and was very disappointed. It was shipped very discreetly from Amazon directly, but it didn't work. I put in fresh batteries and it wouldn't turn on. I even tested the batteries, they were good, but this rabbit wasn't. Unfortunately, Amazon doesn't take returns on this type of personal product. I simple won't buy anything made by California Exotics again. I'll try one of the other brands next time.
Example Output: Negative

Example Input: This desk is definitely worth the money. My daughter wanted a white desk with a hutch and had picked out many over [...] not including the chair. I ordered this one without her knowing and at first she was upset because the hutch is not that big. But once it was assembled she loves it. She is 8 and loves the little cubbies in the hutch. Everything is packaged nicely and there was not one scratch or ding or funny smells. The hardware had everything you needed (no extras) in separate baggies for the chair and desk. I put it together myself in about 1 hour. We did replace the knob with a blue glass knob from the hardware store just to make it a little more unique I guess and it looks great. With free supersaver shipping and no sales tax, there is no better buy out there. Trust me, I have looked!
