It makes good and keeps cold tea.

I love this bottle! It does so much. And keeps your tea hot for you. I got purple, which is my favorite color.

I backed this via Kickstarter two years ago and it's still the mug I use everyday. Only complaint is that it's hard to clean, but it's a small price to pay considering the convenience. No teapot or tea device has come close for me.

Works very well brewing my Chinese teas for on the go. Caution: you cannot lay it on its side as it WILL LEAK.

This is the best travel tea infuser!!!! Leak proof, lid seals tightly. The double wall tumbler keeps the tea warm for hours. The tea is pressed down after steeping …. No loose tea over steeping making the tea biter. Simply the best I have found and I have quite a few. My previous one broke. My fault. (Don’t drop from a high place into a hard surface) otherwise it was getting used often for almost 2 years without any problem. Worth the money!!!! Great customer service when I inquired about a replacement piece after I broke mine, they do not offer replacement pieces but did offer me quite a significant discount. I appreciated the discount given the tumbler breaking was my fault.
