Keeps the hot in one section super HOT, and keeps the cold in the other section nice and COLD! Used it this past week on a 10 hour road trip from Texas to Arkansas, and it kept all the vegetables cold that I kept in the top compartment along with the meats in the bottom. Wonderful product. Now don't put ice in it! LOL. Didn't have an ice chest for an unexpected camping trip so I tried to improvise. It does leak with ice in it, however we were outside so it didn't matter. Used it to pack the other dishes for the end of our vacation... and it works perfectly even after the camping adventure. SO GLAD I PURCHASED THIS!
I recommend this product.
