Multi-purpose jumbo 72-hour Uniheat Heat Pack for Cold Weather Shipping Plants, Live Insects, Reptiles, Tropical Fish and other temperature sensitive products. Protect products from cold weather. 2 PK

Unfortunately I recently ordered two of these and neither of them ever got warm at all. I’m not sure if they were expired or what happened, but I packed one in the hopes that it would heat up eventually, but even after an hour out of the plastic and exposed to air, to my disappointment neither of them ever warmed up.

Did not warm to anything above 80 degrees. very weak. the warm up time is much longer than advertised

Good product. I've used it with both plants and aquatic life.

not as warm as advertised.took more than 30-45 mins to warm up. didnt even last for 48 hrs.

Kept my snake warm during his travel and vet visit so I'm satisfied!

Heat packs had air holes in them and already were comprised and did not warm. Waste of money from this vendor

Just What I Expected

This heat pack NEVER heated up! It was used to ship chicks. They were only in transit 48 hours. Huge waste of money. :(
