I have been searching for a replacement tumbler for quite some time, with no luck. I was glad to finally find a tumbler that not only looks good but boasts to keep liquids cool and hot. I have been using the Joy Jolt tumbler everyday, consistently for about 4 weeks. I love the fact that the tumbler came with 2 sets of lids; one for drinking directly from the bottle and another vacuum sealed lid with a straw. At first the straw's suction was too strong for me. However, after a few weeks, I learned how to used it. I love the fact that the ice stays in the tumbler for about 20 hours. The tumbler can also hold a whole 20 oz of liquid. This allows me to refill the tumbler less frequently than my other cups. I also, really like the fact the tumbler is black, which makes it easy to personalize it. Overall, I am very pleased with this product and I would recommend it.
