Review (5/5): Helps to cool down night sweats
I keep this on my nightstand to help me cool off if I get overheated at night. It cools me down in a few minutes and then I put it back on the nightstand so the gel can get cool again. It won't stay cool all night in a pillow case because eventually the gel absorbs the warmth from your body and you have to set it aside to let the gel cool down for about 10-15 minutes depending on how warm it got. The casing is pretty durable and it hasn't burst yet after a month of use. You can push the gel around a little from side to side and it feels sturdy.
