Product Description:
REUSABLE up to 250 times plus, simply click on the small metal button to activate for 130 degree heat lasting over an hour, and then just boil for 4 to 5 minutes for a completely recharged heat pack, and use it again and again!! Due to improper use and handling, the life of the heat pack can vary greatly, lasting over 400 activations if used correctly, and lasting only 50 if used incorrectly. Therefore, our warranty covers shipping and actual product quality, but we simply cannot guarantee the life of the heat pack, as it is so relative to the care and treatment by each individual.
