Query: Sorry, did not care for this product

While I could get the lift I needed by adding water, the water itself made the pillow feel cold. I tried wrapping it in a double layer of fleece and then my pillowcase but after one night my neck and shoulders hurt so bad from the cool water that I just gave up. Reminded me of the time my waterbed heater gave out. Even a heavy quilt on top didn't protect me from the coolness. I was definitely not happy with this product and would not recommend it.
