I have two complaints: 1) The hole where the liquid comes out is right where your upper lip normally goes when drinking. I find when drinking hot liquids it burns my upper lip, and there is no way to avoid this. I have had other mugs, and this is the first one that has done this. It is because of this that I give it a 2 rather than a 5 rating. 2) It is just too tall to slide under a Keurig coffee maker. You have to lift the coffee maker up to get it to fit.
I like the design, and purchased it because of that. And it does keep liquids warm as advertised.
No, I would not recommend this to a friend.
