Uniheat 72+ Hour Jumbo Shipping Warmer Heat Pack

I use these to keep sealer above freezing in the colder season. Work really well. Very happy, thank you.

Well, it came packaged exactly as shown so im pleased. Havent used yet as keeping for emergency but overall happy.

Great product. They do take a while to heat up so opened one night before, then one next morning and then one on day of travel. Snakes arrived warm and happy after 15hrs.

I used it only for 3 hours today and it’s still warm 12 hours later. My tortoise was very comfy and warm ! I definetly recommend it & will be purchasing more for my travels !

Great product, as expected. Bought these for stand in case of emergency like long power cuts or for vet trips with my snakes and lizards. Used UniHeat before and they are the best out there. Seller shipped very quick and at a great price. Would by again from this seller.

Kept fish warm and cozy all day during a house move

Nothing to add, worked perfectly.

using these to transport african land snails. would recommend.

This product is great!

Used this when I shipped my tropical fish from Oklahoma to Wisconsin in September. She arrived warm and well.

Used the heat pack to ship chicks and they arrived in 48 hours. The pack was warm, but did not feel as warm as advertised (115 degrees) and the chicks were chilled. I don't know how warm it was when shipped so I can't comment on that. I didn't use a thermometer, but neither the box nor the pack were very warm and they got quiet as soon as they warmed up. Maybe my expectations were too high!

We used up our last ones in the last power outage. When the power goes out in cold weather, we pack the snakes up as though for shipping -- pillow cases in insulated boxes, with heat packs. Since we don't have a generator yet, this is the best way of keeping them safe until the power's back on. The long 72 hour time means the packs take a bit longer to warm up fully, but they don't get as hot as short-term heat packs, so they're perfect for keeping the snakes comfortable. I recommend them to anyone who has pets that need supplemental heat, who may need to keep them warm in an emergency. (Just don't put them directly in with the animal, you don't want them to break them open or sit directly on them).
