Igloo Maxcold Ice Block

My use case is a modest size lunch box, holding little more than a sandwich and snack. Does its job to the letter, keeps things cool long enough for lunch time. Usually by the end of the day it is starting to show signs of warming, but, it's an ice pack, we expect this to happen eventually. Mind the size, its size is about as you would expect from looking at it, listed dimensions are accurate. Not disruptively heavy at all, fits nicely in a modest size lunch box. Cools down in the freezer amazingly fast. Of course, always put it in overnight to really make sure it's cooled properly, but in a pinch this thing can cool down fast. One critique that is of zero consequence, after a few cooling cycles it will bulge in the middle. It would be neat if these ice packs were made to have chambers to prevent the fluid from freezing all in its center point, but this literally does not matter at all, just would be neat if they found a way to prevent that.

Pretty standard Ice pack. This brand can fit 6 in the average lunch box. I pack 1 on each side of my insulated lunch box and 2 on the bottom and top. Keeps frozen a long time especially when you use multiple or combine then with other things that are insulated. These keep food from spoiling all day. They are easy to wipe down and freeze again for the next use. These little packs are fairly durable too. They hold up for any job, and can withstand high temperatures for hours. I have not had one puncture or leak on me during transport. They dont take up much space in the icebox either. As far as transport goes, these are versatile outside of your lunchbox too. If your shipping something and you are unable to access/ afford dry ice, a few of these can do the job if its overnight delivery. I had no issues with my local post office when I needed to ship a body butter at summers peak. When my customer received the items she said it was still solid, even after arriving 2 days later! She also uses the packs her self, as she is a busy truck driver. You cant beat this deal for a dollar, not even the dollar twenty-five tree can. Theyre pretty much no fuss. If you want a great product that has many uses, this is for you.

These are fantastic. I use them in a cooler down by the road where I sell eggs. They last for a full 24 hours when it's hot out(Northern Vermont hot, like upper 90's). I have two and swap them out. They are pretty much indestructable. Easy to carry with the big indents. I've tried other ones before that were either flimsy or too small. These are huge and absolutely perfect. They freeze up quickly. Highly recommend.

I am a fan of igloo cooler ice block who used this brand of product for years. I purchased this medium and large size of cooler ice block again. I am satisfying the quality of the product. The outside material seems strong, durable, and should last long. The duration to keep cool is great. The medium and large size design is adequate for storage. The only complaint is that the medium size block deformed a little after freeze, when I stacked in freezer horizontally it may accidentally fall out when door opens.

Good ice packs. I use them every day of the week for my kids lunches. They don't leak and stay cold til I take them out when they get home from school.

Great ice packs from a reliable company. The price was amazing for how good they are. There’s no leakage at all they are pretty dry besides for condensation. They do buldge a little when they freeze but nothing really bothersome.

Works great and like the smaller size. I use for just about everything from office lunch box to packing around food when traveling. Easy to clean and throw back in the freezer.

I have a small RV fridge in my 17' trailer and it tends to get too warm on hot Texas summer travel days. I decided that smaller blocks would allow me to put these around my food in the freezer rather than putting the food around a larger ice block. It works nicely to keep frozen stuff frozen and taking that load off of my fridge keeps the fridge portion cooler as well. So far, they've been durable even on rough roads. They're just the right thickness to protect the food. I'm very happy with the purchase!
