    These are ok, they rip easily and the thicker nordic core packs work much better. I have used duct tape to cover the splits and it is better.
    Thank you for your feedback! We’re sorry you did not prefer this product. For recommendations, please contact our Customer Solutions team.
    Great for those casserole bags so I can keep hot foods hot. There weren't any instructions provided, but I microwaved it in 30 second increments (1000W) until the pack was hot (about 2 minutes).
    Great product. I use two frozen packs on the bottom of my insulated food delivery bag. They staty cold for a long time and provide added stability to the delivery bag.
    Great to have for catering. I use them in my cambro boxes when transporting hot or cold food. It keeps the food close to temperature for the time needed.
    I was skeptical when I bought these hot/cold packs but I had a large event that I would need to keep some food cold and other hot. I was happy that when using for hot and cold the foods stayed within safe temps. used in a holding unit.
    This multipurpose pack is great - it can be used to keep things either hot or cold! Stick it in the freezer to cool it down or the microwave to heat it up.
    I have been using these for years they keep my cold toppings cold at my shop. Works Very well when you freeze them and uae under your cold food
    I used this in my catering containers. They were wonderful. My desserts stayed cold for hours. They were of good quality and i have no doubt will last a long time.
    Works OK. I had to go back on the website to figure out how to work since it did not come with any instructions. I think that was the downside. When I heated up to it's recommended temperature in the microwave, it did not seem to keep my food as hot as described. The jury is still out on this one.

    Perfect for the bottom of my carrier! Provides a perfect cooling base for foods that must be kept cool. I highly recommend it. Would order again.
    There are awesome! Keep foods nice and hot! We use them daily in our kitchen and on delivery. They help us to maintain safe temperatures of our food!
    We used these inside our insulated delivery bags. The packs keep the food warm for an extended period of time. I'm looking forward to testing the cold pack capabilities as well.
    so these microcore heavy duty thermal hot and or cold packs are actually amazing and stay cold and hot for a very long time !
    The Microcore 14 x 10 hot or cold pack is a great addition for our catering needs. We haven't used it yet for heat but we have used it frozen and placed the pack in our cater gator. It kept the desserts cool for over 3 hours. Can't wait to try it heated.
    These thermal packs have been a lifesaver. I have a food truck and am very conscious about maintain proper temperatures which is why these were purchased. They are now a part of the daily packing process. We do use ice chest that plug in and run off batteries but especially during hot summer months these help us maintain temperatures, especially if cases have to be open and closed a lot. Am ordering more for our growing business!
    Great to use in cooler bag to keep the food colder for picnic. Also it’s great that this thermal pack can use for warm food and lasted quite warm and long. Will definitely buy more for my catering business.
    We have been using these inside our CaterGator and in our Insulated food delivery bag. They do a great job and stay frozen longer than I thought! Nice product and we will be ordering more soon!

    This hot/cold pack kept the food warm for hours. Its an expensive and reuseable way to keep food hot for anyone traveling or for caterers.
    Love the size of this thermal pack! It is very good for holding smaller size pans and dishes that have to be transported in a food delivery bag.
    We have huge coolers we transport fresh food products in and these are a perfect shape, do not leak and stay cold a long time.
    The Microcore pack can be easily heated in your microwave or cooled in your refrigerator or freezer. They are re-usable and handy for hot and cold catering. We use it routinely to transport cold or frozen desserts to events. These are safer than gel. They are filled with non-toxic liquid. They heat or cool in the freezer evenly, and can be placed in any type of container for continued heating or cooling
    Great price. Value is awesome. We use in our food carrier bags to keep our pies cold. Lasts for several hours in the summer heat
    If I could give these item more than 5 stars, I would! By far one of the best products that Webstaurant has to offer! This thing will hold cold and hot foods for a long time! A must have when transporting food to a far away location!
    The wormers are the best I have ever used and we us this item all the time!! the cost is out of line for them but they are good
    These thermal hot packs heat up very quickly. We put them in the microwave for 3-4 minutes and they are ready to go. I wish they held their heat for a little bit longer, but besides that, they work well.
    We absolutely love the versitility of this product. We use it inside our Cater Gator to warm it up or cool it down for our foods. It is fantastic, because you can use it for hot or cold. I've never seen another product like that.
    I ordered this product because i have some cold packs that contain "microcore" inside. They are pliable when frozen and when thawed. These are NOT pliable when frozen. They are like rocks. They work well but are not flexible to conform to what i needed them for.
    this is a great addition to the insulated delivery bag that I purchased! got to use it tonight, put it in the microwave for a few minutes and it's good to go. love how versatile it is, can be used either hot or cold
    These things are great. I use them when I am defrosting my ribs and chicken. My cooler stays under 40 degrees for days and keeps everything in the safe zone. I ordered 4 and might get some more.
    This is a good product to keep at the ready - in a pinch you can add some coolness to your cooler. The downside is it doesn't stay frozen for long. Well worth it to prep a cooler or hot case.
    These are great to have on hand for cooling hot pans, and also transporting cold food in our carriers - they are durable and well worth the money. Thanks!
    I put this into the microwave for about six minutes. I flipped it over half way through. When I saw it start to puff up I took it out. It checked about 190 degrees and now it's ready!
    I got this large thermal pack to keep my foods hot during transport. I also got an insulated tote from Webstaurant that has a built in pocket for heat packs (item #424DB185BK). This combination is perfect for my potluck items and was very affordable.
    I did not get to test the microwave to see how hot the packs get and how long but I can definitely can say they stay cold four about 3 - 4 hours.
    Super easy to use and absolutely a must have for larger coolers. It freezes well and keep the temperature long enough. We use for all food transportation. Works great.
    We took a chance on thses cool packs! And are we glad w did! They worked perfectly in our coolers, kept our product cool and fresh the entire day at our Market!! Will diffently be buying more!!
