Let me explain something. I am really clumsy. I have two delicate tumblers for when I want to feel elegant, and two stainless tumblers because I’m also a realist. This is my favourite of the two. Why?
I’ve dropped this sucker a number of times and not had to worry about it shattering or denting: it has one scratch on it roughly the size of a pinhead and I take this everywhere.
Like a lot of silicone seals, mine will try to leak if I’ve overfilled the bottle past the ring. It has kept hot tea hot for around 4-6 hours and ice tea iced for around the same time (sometimes there are even little bits of ice clinking around later).
