I had been shopping around for ice packs for a new rotomolded cooler I bought a couple of months ago. I've tested ice with this cooler and it as lasted a solid 5 days with ice to spare, which is more than enough for my intended use. The ice-packs were to supplement the ice and also to use it as a primary to keep things cool.
I found Cooler Shock on Amazon and got the clear container. The container seemed a little flimsy when it arrived as if it would break when dropped. But after filling it with water and getting a gel solution, it seemed to hold its shape a little better.
Instructions were followed the first container and added cold water from the faucet, it took a while for the power and water to mix and stood their shaking it much longer than I expected. I then mixed the powder in the second container and added 2 cups of WARM water to the powder and it dissolved and mixed much faster. I added 2 more cups and continued to shake it and then topped it off with the final 3 cups. After about 30 minutes, the gel then expanded to fill any gaps and the solution in both containers was ready for the freezer.
Long story short, this ice pack seemed to last a little longer than the RTIC brand. The freezing process was more even than the RTIC, where the RTIC ones bulged. Both brands were kept in the same cooler for about two days that held a consistent 38 degree F inside the cooler. After the two days, the RTIC started to lose its ice form and you can feel the gel move around. The same was for the Cooler Shock, however it wasn't as bad as the RTIC. It would be probably last longer had I primed the cooler and filling the space with other cold items. But two solid days of below 40 temps was good enough for me.
This testing and comparison between Cooler Shock and RTIC ice packs isn't the most comprehensive nor is the validity of the testing methods were equal to one another, but I figure I'm going to be using both at the same time anyway whenever I use it. As for using the ice pack with actual ice, I'd need to do that another time.
