The quality of this mug is equal to the higher priced ones. Keeps things hot super long as I had for gotten it on the counter before work. Came home and it was still hot.
Second Miir product purchased from Loon. Very pleased. Keeps coffee extremely hot.
The cup keeps the coffee hot for hours, but it is very slippery. Hard to hold on to. Easy to drop. It does seal up coffee tight and does not leak.
It is small but very handy and keeps things hot and cold for so long! Well made, would order another. Stickered it up already!
Miir is a great brand and product. Perfect for my morning coffee on the way to the river. The wife even thinks it's cute which is a first for all my fishing stuff.
