I've been using these heat packs for almost 5 years and have yet to have one fail on me. The pack just enough heat to keep fish warm durning cold months. I trust this brand.

I don't think these things last 72 hours. Everyone I have rec'd has been dried up with no sense that they have been that way for just a short time. I am talking about relatively normal trips and not long ones which I would probably try anyway. Prices are charged all over the place - more of a profit item than an item to insure prevention of freezing. However, I will often use them rather than take a chance.

Highly recommended heatpacks rite as they stay warm for longer then 72 hours which is great as if priority mail is the method used most likely they will still be warm up in delivery, if packages correctly with a Styrofoam lined I'm the box these heatpacks can bring the inside box temp up to safe levels even in below 0 temps so again this are great to use for any live shipment that requires heat. HIGHLY RECOMMENDED!!!!!

Great For shipping Live Plants & fish. Sometimes it's too large for shipping small live bare root plants. It can cause the shipping to go over First Class weight. Adds about 8 oz. so I just cut them in half and tape the seam.

We use these when we ship young chicks or hatching eggs during the colder months and also when transporting young birds for delivery. Have used over 100 and have only ever had one fail. You will need to start activating the packet at least 30 minutes prior to using...they take a while to start heating up.
