### ⭐⭐⭐⭐⭐ My old one does not leak. New one does. Both hold heat well.
*by B***6 on December 10, 2025*

I bought this tumbler over a year ago and decided to buy another one. I like everything about it but most of all it didn't leak. The lid has a small flip over cover that snaps into place never leaks. This new one was slightly different. The flip closure did not snap closed. When I turned it over and water poured out in a small stream. I decided to fill it with hot water to see if the lid material would soften and mold itself to seal. I made sure the cap was firmly screw in, closed the flip cover firmly on the lip, then turned the mug over. Water came out again but then slowed to a trickle and eventually stopped. The next day, same test, leaks about 2 drops per second. Both old and new kept hot liquids hot. Started with 207 degree hot water. One hour and 15 min later about 147 degree. Still hot enough. I like the tumblers. I have confidence that one will not leak either while in the cup holder while driving or in my gym bag ( would still place it in a medium plastic bag ). The other one that leaks, place in a cup holder or in your hands only.
