I am happy with the construction of this mug, but NOT with the way it holds the heat! The first day was somewhat okay, and it held the heat for about six hours total. But now after using it for about a week, it seems to not be holding the coffee more than a couple of hours. The only reason I ordered it is that I needed a new travel mug. I'm not happy guys. I bought it through one of the catalogs I have an account with. It has an emblem on it, (BulbHead.com) I consider it false advertising.
Bottom Line: No, I would not recommend this to a friend
