Review (3/5): Pay attention to the size of the pad.
So much potential - why so small? Cooling area is only about 7 x 11. Draw that out for yourself and see how much space on the pillow is taken up. I underestimated how much coverage that is. Lesson learned. You open it, and it may seem to only have gel on one half of the pad. Work with it to get the gel over to the other side. I like the feel of it and am glad it isn't a wet cooling product.
