Works great, we use it in our Yeti and love it.

1. Fairly inexpensive2. Quality materials, feels very sturdy3. Stays frozen all dayI had my doubts but I added water and froze them for about 2 days. Around 8am I threw 1 (which fits absolutely perfectly in my yeti hopper) on the bottom laying down, 3 bottles of water and 5 cans of assorted drinks, and then threw the other 1 on top with about maybe 20 pieces of cubed ice from my freezer to fill the gaps on the sides.The drinks were room temp. In about 3 hours I checked and the drinks were ice cold. The ice cubes were still there. Hour 5 I checked and now there was a thin layer of ice/frost covering the ice packs. These things are crazy. Lasted all day, still frozen, and drinks are ice cold, I AM SOLD.

These things really retain the cold. They are easy to handle. Good quality and value.

I believe that you get what you pay for. These are worth every penny. My refrigerator went out about a month after I bought these cold packs. The new refrigerator did not arrive for 3 days. I just put these cold packs inside the old refrigerator until the new one arrived and it stayed cold enough that I didn't lose any food. NICE!

This is one of the best ice packs I have owned. I used it this summer in a soft sided backpack cooler and it stayed frozen all day on the boat. I am vey impressed with the performance.

Cools a cooler quickly so if you have an insulated cooler that is good quality this would easily get to fridge temperature quickly. My small cooler maintained the temperature with this for 2 days max

These are awesome. Fit perfectly in my cooler. They come in a variety of sizes.

These stay cold for a LONG TIME. They come empty so you fill with water, shame to activate the freezer gel inside and then freeze like a normal ice pack. 4 of these in a 30 gal cooler kept it cold for 24 hours.
