Works Great!
This pad is very small, but perfect for any spot. I get real hot at night sometimes so I just grab this thing and put it directly behind my neck for 15 minutes and I feel cool again. You can put it in your pillowcase, but it's small so it moves around and it feels less cold. Also works perfectly on your feet or legs! It does not stay cold for hours like it claims. It stays cool for 30 minutes or less. When it warms up toss it on the floor and within a few minutes you're good to go again. For extra cold you can put it in the fridge. Overall, I think this is a great product. It cools me down which is exactly what I wanted.
