1. No. It is not nearly hot enough to burn anything. It cannot reheat a cold cup of coffee.2. No. You have to remember to shut it off.3. Yes, it is big enough for most mugs. Even my extra large mug fits ok.

It will not burn your desk... It does not have an automatic shut off ... It fits most sizes... I have very large coffee cups and it works great for them all

Also it keeps coffee very hot down to the last sip ... Just be careful not to leave it on and forget and set something on top of it

There is no auto shut off, but it won't burn your desk. I have accidently left mine on at work for long periods and there was no problem. And yes, 3.5 mug fits. I love mine.

base diameter is 2.5 inches and it stays that diameter for almost 2 inches up the cup before it slopes wider to 3.25" at the top. This travel mug is expensive compared to other models but it really does keep things hot, so hot that I have to break my old habit of pre-warming the cup with hot water or otherwise you cannot drink your coffee for an hour as its too hot. Two negatives; says do not put in the dishwasher, that is a pain to me and I don't want to risk it and damage this $25 mug, also when you tip to drink the flip-top lid touches your nose unless you tip your head way back to drink. Its a good cup but it has flaws so in hindsight I don't think its worth $25. Hope this helps... base diameter is 2.5 inches and it stays that diameter for almost 2 inches up the cup before it slopes wider to 3.25" at the top.

I do not recommend this mug. It's very top heavy and tends to spill easily. The sensor device and its heater stop working properly after a short while. I threw mine out.

I actually bought them for gifts & specifically bought the kind without an automatic shutoff so a drink would stay hot till they turned them off. I am told they keep a ceramic mug filled with coffee very hot. If your tumbler is not heat resistant... like plastic or even some glass, I would think this item would not be for you. If you want something that keeps a drink HOT, use a different drink container because this item works really well. Hope that helps.

Hi there! I've had mine 3 years. I used it primarily for camping. I own several machines. Don't ask. I've started using this one in the house as primary. I love the size, coffee is really hot, programmable and auto shut off.

The biggest flaw I found is that the mug is not well insulated and dissipates a lot of heat. I bought a better one at Bed, Bath and Beyond and now my coffee stays hot for hours. What is your specific concern?

Yes, it gets very hot actually and automatically shuts off after 30 mins. It has everything a large coffeemaker has only in a small size.

While I used mine I was able to use a small 3' mug. May still have some room for a 3.5-3.7' mug. Hope this helps.

Yes. It continues to keep coffee hot for about 2 hours and then will automatically shut off. You can then turn back on if you wish. Have never had burnt tasting coffee. I love mine!

Not sure if it is, but I can state that 1 min in a 900watt caused the mug to be EXTREMELY HOT but the coffee was still cool. I didn't handle it for several minutes until the mug cooled because I was afraid it would fall apart. Love the mug, but I will never put it in the microwave again...

The mug will hold up to heat and the handle remains cool. However if your knuckles touch the outside while holding, it'll burn. I tested with spiced cider.

I don't have this anymore, it didn't keep my coffee as hot as I like, found I don't drink the coffee as quickly as I thought. I got a different cup warmer that I am very pleased with, enough that I now have 3 of them. Get the Disney Mickey Mug Warm. I think you would be happier with it than this one.

Not really. It's just designed to keep hot stuff cooling down slower. It might heat cold water in an hour or so but not hot enough to make tea and that amount of time could damage the mug.

Laurie, the actual heating portion is almost 3.75" A mug with 4.5 inch base would be way too big for this to keep warm.

Hi Soultrain, I have purchased 3 mugs recently, which mug are you asking about? The question came to me without any details from Amazon.

No, it gets too hot! And the belt does not adjust well to other shapes! I had a hard time with the mugs.

There is one that keeps the coffee hot on the 12 cup side, with an automatic shut off after two hours. There is none on the one to one and a half cup side. I have had this item since Feb 2013, use it every day, and sometimes twice a day, and so far have not had any problems with it. I hope this helps you.
