When the ache/pain in my upper back won't stop, I always turn to this product. It takes away the pain almost immediately. It is adjustable and comfortable to wear. I love it!!

positive

I had problem with the 2 screen protectors, any of them paste well on the screen. Very disappointing because I also bought the complete screen protection and I hope not happening the same thing...

Ex Output:
negative


Ex Input:
This watch is really big which, when I first opened it, was a bit of a shock. But I decided to keep it and am now very happy with it. I can easily tell the time with out my glasses. The light works well so it is especially helpful when traveling and there is not clock in the room. The large size is especially helpful when you are checking the time at 200 AM. I was able to get the band reduced for $10.

Ex Output:

positive
