We bought this cooler for the R,V. It works just as advertised, keeps ice three to four days. Size is excellent also, tall bottles and cans fit in with no problems. We put 40lbs. of ice in cooler during a Labor day trip and all stayed cool for four days. Recommend it to anyone wanting a sturdy long lasting cooler.
The fact that they have different colors and sizes is amazing. The straw is a little weird at first its like rubber material, but after a week of use you will be used to it. Other than that I would give this water bottle a 2 thumbs up!!!
