Question: Can this mug actually boil water to the boiling point?
Document: I like the mug and it warms the water pretty quick, the clock showing inside temprature is also very nice.My only concern/suggestion is why can't this be a little bigger?
My wife has and she say's it's  so so .I will be back when I check this mug out further myself,  "The most important I will test that the coffee stays  hot for 40 min.? "This should be about all I would expect 160 degrees  for 40 min.RobertOne week later !!! !My test of this coffee mug, Added  hot water plugged this into my car lighter socket ( always on ) car interior temp. 64 degrees.
later,  checked temp.the water was now at 158 degrees  drove home 60 min has passed total time start to end. 138 degrees.Step 2 in the house added 199 degrees water sitting on counter and 45 min. later the water was 158 degrees still quite hot Too hot to the touch.So I would say the mug worked as well as I would expected  it to.Five star on the temp.Two stars on the design .Robert
Other reviews said this fits in a car cup holder, but I found the cord prevents putting it there in my car. It takes a looong time for the water to heat from room temp to tea time.
I was dubious, afraid that cuteness was the main selling point, but it appears to be well made, heats very efficiently, doesn't need to be plugged in for long to reheat cooled coffee. The temperature gauge isn't 100% reliable--at times seems that when there's not much liquid left, it may not register correctly.
i gave it as a gift. the recipient was very pleased with it. the mug works just as expected to
I gave this mug to my daughter for Christmas. She was excited to get it, and I have heard no negative comments.
Didn't keep coffee warm at all. Complete waste of money. Coffee was cold faster than in my non-heated mug at work.
I bought this mug to carry in my car because you can plug it into the cigarette lighter. I've only been using it about a month and so far it has worked great.
i love the overall looks of the mug , i don't use yet but , boy it looks so retro ja ja my co-workers gonna love it
Answer: I bought this mug and I do like it.  As to the boiling point, I'll say this, it is hot enough to burn you tongue.  I don't keep it pluged in any longer than necessary.  I do recommend this mug.  The thermostat on the side will tell you the range of temp.
