How many uses can I expect to get?

In theory, the number of times that a HotSnapZ can reused is infinite. However, the consequences of real life usually take their toll on HotSnapZ at some point via wear-n-tear, being torn, stepped on, forgotten in the boiling pan or having one of yo r friends walk off with them. So, we expect and tell the average user to expect 200-300+ uses if properly used and stored.

How long does the heat last?

Heat duration depends on the product's size, how the product is used, & how well the product is insulated during use. Our larger Rectangles, Neck and Shoulder products are rated at 2+ hours of heat. Our green rectangular Pocket Warmers at 50-60 minutes each and 30-40 minutes for our Round Hand and Heart Hand Warmers. Extended heat times are achieved by having some extra ones in reserve! Remember....HotSnapZ are REUSABLE!
