Input:
Question: Is it really microwave safe?  I've seen some that say they are and when you get them home, they are not.
Document: And it IS beautiful - never thought I would say that about a travel mug! But I would be seriously upset if this got cloudy on me so I am being very careful. These folks have something here, but they need to work out that last &#34;detail&#34;!
This Mug is so clear and feels so nice in your hand it is hard to believe! It has really nice heft to it and it has some kind of bottom that prevents it from moving around unless YOU move it. (Why doesn't every mug have that?) It is very nice to drink out of. The only thing that caused it to lose that final star is that you cannot put it in the dishwasher! And you are even warned not to subject it to sudden heat.
At first I thought &#34;stunning&#34; was really over the top, but it really accurately describes this mug! My husband put the 'Energizer Bunny' decal sticker on it that I also bought at Amazon.com, and now he can keep 'going, and going, and going.' The gasket top is a state-of-the-art seal. It's the perfect size for a hand and a cup-holder. It would make a great gift. I will buy more.
My nose happens to line up perfectly with the tiny air hole in the lid which can hinder the flow when I'm taking a drink. Outside of that is is a very nice mug and is as advertised.
I ordered the lovely clear version and am using it as I write this. Like another reviewer posted, I am hoping that the clarity of the mug remains and that it is as durable as it is cool. Drinking some hot coffee out of it and it's so comfortable in my hand.
And the fact that it's 16 ounces makes it even better. Money well spent, at this point.
Answer: Had no problems with it in the microwave...Works as advertised...
