I got 3 of the same coffee cup in 3 different colour! Started to use 2 weeks ago. Realised that the lid ( near the sipping area) is a bit hard to clean. One of them already have a slight crack inside.
I bought a ceramic travel mug some time ago, but it has a silicon lid, which is not the best. Having bought THIS travel mug, I am so happy with it. The glass lid feels wonderful to drink out of. And, because of the double-glass layer, it doesn't get too hot to hold, yet the coffee still stays warm. Perfect!
