11 hour drive
We brought popsicles from AZ to UT never needing to add ice. My wife used some special types of ice packs and they put those packs between the popsicles, but it being the hottest time of year, we were happily amazed at this cooler. Now we use it all the time, even for grocery shopping. Great find and definitely worth the price!Only frustration was it was delivered late and didn't have inside specs listed (at least at our time of purchase).

Keeps ice for days a very good deal

Ice retention time extremely poor
I have used this cooler on several UTV trips and I would not recommend. I have filled it with ice and food and put inside the cab of my pickup when travelling to sites for UTV Adventures. The ice is mostly gone before you arrive. In 2 days you have no ice at all, you have a small amount maybe 50% left when you arrive after the 1st day. Over rated product!

NOT MARINE GRADE
The cooler itself works “okay” in terms of ice retention, but it is cheaply made and starting to break apart and expose the foam interior (see photo)I own a seafood company, so my coolers get heavy, “marine” use.Stinks because I bought a bunch to replace my older igloo coolers. The older models definitely held up better. I hope igloo doesn’t start to sacrifice quality for profit or I’ll be looking for an alternative asap.

This does not hold ice for long!
I THOUGHT.....I was buying a cooler that would keep ice for a few days, I know, I know it's not a Yeti, but this this was inside my truck, out of the sun and my old Igloo that was in the sun kept ice longer, go figure. Luckily I got it as a discounted item and all that was wrong with it was a little dirt on it. I'd pass on this cooler.
