works very well

This thing is very nice and comfortable. It comes with straps to help keep it in place. It freezes pretty fast. The plastic bag keeps it from developing frost on it and the soft part feels just right on your skin. It works as intended.

Excellent quality and worth every penny. I get flare ups from going to chiropractor, this definitely helps with recovery

This ice pack is a godsend! I have degenerative spine and lower back problems and this product does a fantastic job. The pack is made extremely well. I keep it in the vegetable bin in my refrigerator. It is cool enough that way. I don't need it frozen. I awake in the mornings sometimes bent over and hurting from the bottom of my neck to my low back. Fifteen minutes of me lying with this along my spine and lower back and I can get up and walk upright again. Worth every penny to me! I don't see the need of my replacing it again either. It's that kind of quality!

Great coverage for back.
