  1. fresh product 5 Star Review

    Posted by on 2nd Jun 2020

    I have purchased these heat packs for years for shipping. But many times I have gotten groups of them that expired within 6 months. These are the freshest ones I have ever gotten and are good for 2 years.It's so nice to find an inexpensive source for these with fresh product.

  2. Works as Described!!!! 5 Star Review

    Shipped a trio of guppies in 37° Temps in an insulated box with the heat pack and they arrived at their destination with bags still warm and water was at 74°... Definitely would recommend for any breeders that need to ship in colder temps.Works with a well insulated box.. Thanks Heat source price was great as well.

  3. works as directed. great price! 5 Star Review

    Was shipped fast and product is what it is. Know your tools. This does require oxygen to work. It does need to warm up 1 hr prior to using... ect.. all on the label.

    I have recorded these packs (at max insulting) to raising temps as much as 25 degrees. So wrap and package accordingly. Also have reports of them heating for an excess of 72hrs.

  4. Works good if O2 is available 5 Star Review

    Posted by on 24th Feb 2015

    I use these in my business to include with orders to keep my products from freezing. They do work good as long as they have enough O2. I learned the hard way sealing them in ziplock does not work unless you put holes in the bags and leave the bag open. Also they can't sit outside in the freezing cold long but as long as the customer brings the package indoors soon after delivery then they can handle below freezing temps.

    Our business ships african night crawlers all over the United States and these heat packs keep them warm until they get to their destination.
