Portable Large Cold/Hot Pack (2-Pack) - Made in The USA

These kept my food really warm in my travel container for a couple hours. The food stayed hot until served.

Good quality. Works well. Very hard to find, glad amazon had them!

worked well for keeping my dish warm

I bought these as a replacement for some that came with my Pyrex Portables (the hot pack exploded in the microwave). I've used it only once and it did a great job keeping my dish hot on a 2-hour drive (of course, it was hot from the oven, as well). I hope it will hold up for many uses. I thought it was a good value and I like that I can either heat it up OR freeze it -- I don't have to use it for one OR the other, the way I had to with my old packs.

Real Pyrex items.

I've been sending my kid to school with homemade versions of the school hot lunches. This has been an absolute God send! I heat the hot pack in the microwave for 2:50 mins, then another 15 or so until it puffs up, remove with oven mitts, and put it in his insulated lunchbox right under his stainless steel bento box (we have the "LunchBots" brand). I was worried it would be too big, but it's not, it scrunches in there perfectly. I cover the hot pack with a paper towel because it's ugly... but boy does it stay hot! I put some leftovers in there yesterday and he said it was like eating straight from the restaurant, perfectly warm. HIGHLY recommend!! My only concern is how durable they are for everyday use - because should this thing ever burst open while I'm taking it out of the microwave, I could get burned pretty badly. Curious how long they have lasted for others?? So far so good, but it's only been about a month. It gets used 5x/week. I guess I should be alternating since it came in a 2 pack... maybe that way they don't get stressed to the point of breaking as fast... but anyway, hopefully it never will break!

Keeps food warm and keeps food cool! Love this product when traveling with food. Well worth the money, no smell, and just the right size!

My pyrex carrying case is 23 years old! It still works, but the original hot/cold packs have lost their vitality. I purchased these as replacements, and they work great. In addition to keeping hot casseroles and baked mac and cheese warm while transporting to family dinners, I use the hot packs to keep my soups warm when I carry lunch to work. I don't typically use the cold pack, but I imagine they'd work good when frozen, too.

They are great to keep food warm or cold in the insulated carrier.

Use this cool and warmed

Froze the product and used only once. Corner tore and spilled the gel all over casserole base. Very disappointed due to the price and name.

Too expensive for what they do.
