Cold-holding bricks

First introduced to these when I received one of these brix with an online shipped food order. Did such an amazing job at maintaining freezing temperatures that I sought out more of the product. Soooo glad I did - they came in VERY useful when my refrigerator failed recently and I was forced to put everything into coolers for over a week. Even with frequent opening of the coolers, these brix stayed frozen and kept things cold. By comparison with several other refrigerator packs in use at the same time, they did the best job over the ten days. The 9x4" size of the brix are good size, very solid and not floppy even when not frozen. They are easy to fit in large coolers. Almost any freezer pack can work for a few hours but these brix easily held up for 18-20 hours and were still really cold and quick to refreeze. The brix easily stay frozen for 2-3 days when the coolers weren't opened frequently and searched through.

Kept steak cold in mail for almost four full days!

I am so excited and have to leave a great review. I mailed a bunch of refridgerated goods to my brother including a Delmonico steak through USPS. I used a regular cardboard box, then I doubled up on insulating bags (the silver ones) then put two of these frozen bad boys in a plastic bag and then put them on the bottom of my insulated bags. Added my cold goods, folded over the insulated bag and taped it down, then I threw a third insulated bag over the top of the other two bags to make sure it was sealed from the top. I mailed this on a Monday afternoon. It arrived Thursday at 11 am and my brother said it was all still cold! I’m so pumped. Awesome product!

Keeps things cold for hours

This block is big and fairly thick. If you’re looking to keep a small lunch box cold, I suggest one of the smaller sizes, like this Polar Tech RB15 Re-Freez-R-Brix Foam Refrigerant Pack, 4-1/2" Length x 4" Width x 1-1/2" Thick (Case of 6) . I pack one of these big blocks in my large lunch container (slightly smaller than a small Igloo type cooler) and when I get home from work it is still cold. They definitely stay cold longer than any other ice pack or gel pack I’ve owned. One word of caution though – the packaging is susceptible to opening at the seams, and if you’re not careful, also tearing. I found this out one day when I saw some green liquid at the bottom of the lunch container when I was cleaning it out. I didn’t want to go through the hassle of returning so I just super glued it tight. Besides that, these blocks work great.

Stayed cold for road trip.

I put two of the bricks in a 1.5 x 1.5 x 2.5 foot cooler on a 10 hour road trip in July in the South. They arrived still cold and partially frozen. My mom took them out of the cooler and placed them on the kitchen table at about 6 p.m. The next morning, she noticed that, the side touching the table was still quite cold. For comparison, I put several of those frozen plastic blocks filled with the blue liquid in a different, smaller cooler and those were all melted after the trip and not as cold as the bricks. Not the most ideal to use for shipping things you are trying to keep cold, only because they are heavy. But they should do the job for short shipping times.

Love them!

Your browser does not support HTML5 video. The packs work great. I use these everyday. I would make sure to keep these in a plastic bag to protect the plastic coating from tearing. Otherwise, you will be very pleased with this purchase.

Long Lasting

I purchased 3 of these to put into a soft sided (trader joes) cooler, which I transported 2 frozen full size key lime pies in from Florida to New Hampshire for Christmas. They kept the pies frozen all day long and the bricks were still mostly frozen the next day, and they were only in a cheap soft sided cooler bag. Worked fantastic!!

Game-changing Ice Packs? Yes way!

These ice packs are supremely valuable in our household! With a little guy on continuous g-tube feeds, getting up to re-fill his milk bag every few hours was exhausting. When we discovered these ice packs, it was a game changer. These ice blocks keep our little guy’s milk cold all day! No more refilling around the clock. Love them! Will never use anything else.

Good for the price

They are thick foam-ish feeling inside and lasted frozen a regular time and at a cool temp for a few days but does produce A LOT of condensation when melting. Also the plastic can be easily punctured beware. I put one on the top draw of the freezer and when I pulled it out it had a small tear. I eventually used 2 for shipping chocolates in an insulated grocery bag.
