### ⭐⭐⭐⭐⭐ Great buy
*by K***T on January 19, 2026*

Love iiiit!! So easy to press a button and the lid pop up for quick and easy sipping. It has a great seal but the downside of that is that it's a little hard to unscrew to refill. This isn't a problem; I love that it's leak proof. A great buy, for sure.
