Ex Input:
While this book is very good on providing scripture quotations, the commentary is dated and extremely biased. If this book were to be shared with people of non-Mormon faiths, they would become very defensive and rightly so. The author's invective toward the Catholic faith is appaling. Many Mission Presidents do not recommend this book. It could be dangerous in the hands of the untrained.

Ex Output:
Negative

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.

Ex Output:
Negative

I bought 2 of these hoping to show my kids one of the toys I had growing up. Wow, these are straight CRAP. Why would someone produce a product that SUCKS this much?!! The clip that holds the rocket to the pump doesn't hold the rocket on. The O-ring is a dried, hard, brittle piece that doesn't seal. Then, when you get past ALL that crappy-ness, the pump shaft will either pull completely out, bend like a pretzel while pumping, or leak water into the pump itself! I got three launches out of 2 of these. I was more disappointed than the kids were. Boooooo!
