This is really nice especially since the inside is stainless steel as well. Keeps my tea nice and warm. The rubber hand grip is a cool feature. Very safe, and doesnt spill at all.
The travel mug looks and feels solid. I have owned 2 and both allow liquid to be trapped between the outer shell and inner metal liner. After a while, they smell so bad that the only thing you can do is dispose of them.
very poor quality....I bought one of these mugs a couple of years ago and was very satisfied. The new ones I just bought are not the same quality. the top plastic does not fit securely to the stainless steel and water pools between the cracks. After one washing the top is very hard to thread back onto the cup.
Love it. Keeps coffee warm for my commute of 30 miles.
I've had several of the Craftsman Copco mugs and they have always been great. I've done the sink test. I fill the mug with coffee, close the lid and hold it upside down over the sink. I've never seen even a drop out of the mug. I haven't had the same experience with other coffee mugs that say they are spill proof and leak proof.
