I had placed a huge order for my children for christmas. I was so upset when my children got the movie and there was no disc at all. so my bad review is with the company not with Amazon since they were kind enough to fix this problem and send another movie free of charge and free of shipping!! Thak you!

Ex Output:
Negative

I didn't much care for "On The Road" after the first 50 pages or so and i'd pretty much thought that this great "Beat Writer" was nothing but hype, but after reading "The Dharma Bums" I now believe Kerouac is one of the greatest writers of modern times. READ THIS BOOK!!!!

Ex Output:
Positive

I had another infrared massager before this one that I used for years to help with sore muscles and a nasty TMJ condition. It finally shorted out and I bought this product just a few weeks ago. I had one of the worst headaches of my entire life yesterday and was using this on my jaw when I most unfortunately fell asleep. I guess muscle relaxers and vicodin will do that to you. Anyway, when I woke up, I found that I had rolled over and the infrared massager was underneath my pillow. It completely melted and burned through my sheets and a couple inches into my mattress. I had fallen asleep a few times with my other infrared massager with no consequences so this surprised and dismayed me. This is not a safe product - it either needs to be made of sturdier material than cheap plastic or have a timer on it - I would certainly be willing to pay the extra money to not have to worry about setting fire to my house or burning myself. Sorry - can't recommend it.
