What type of mug/cup do you tend to use it in? I.E. ceramic or steel travel, plastic travel.

Either of them is OK, but a metal cup would probably get too hot. I would use either a styrofoam or ceramic cup. The danger of electrocution is about the same with metal or an insulating cup since if the heater fails it could electrify the water.

I only use a ceramic mugs. The heating element gets pretty hot, so I personally would not use a plastic container. I don't know what the ramifications are of having a metal heating element come in contact with a metal container, but there is the possibility of the metal getting hot and causing the housing to heat up, thus causing damage. I would stick to using a container that does not melt or conduct electricity. I hope my ramblings help. Be safe!

I left the cup at a function but I do know the handle did not fit well in my coffee holder in my Subaru. I like my new cup much more. LiquiSeal Travel Mug in Silver by OXO

should be it is ceramic, bought it as a gift did unpack it and looked at it, appears to be a normal coffee cup that is designed not to leave rings.

I had the same concern - couldn't figure out why the thing didn't work as a traditional "commuter" mug. It isn't. Think old-school thermos. Unscrew the top and drink or pour. And be careful if driving - the liquid stays hot.

I gave this as a gift to my mother in law and it's her go to mug. Loves it! She does put it in the microwave often. No complaints!

do not microwave this cup. the handle must have metal in it. i burnt myself taking it out of the microwave thinking it was like any other ceramic cup. the cup itself only heated up with the coffee inside but the handle itself was extremely hot.

I think the mug is made of aluminum. The exterior is color painted. The interior has a very smooth non stick coating. I wash it in the dish washer every week, no problem so far ( 6 months ).

The cup gets hot, not as much as a ceramic cup, though. And the handle doesn't get hot at all.

I believe so. I use a ceramic mug but I would use a metalic one if I had one that had thin walls.

I've owned two of these mugs for several years. There are no markings on them to specify the nature of the glass. However, I use it in the microwave to make boiling water for tea without problems, or pour boiling water into into it. I replaced my first one because I accidentally knocked a small chip off the lip; the glass did not shatter so it is probably tempered at the very least.

I would not recommend putting this mug in the microwave. The ceramic handle for this mug appears to be hollow and would most likely crack. However it is a beautiful mug !! I love mine.

Yes the cup can be used in the micowave but and the handle does not get hot. The finish is smooth. What this mug is not is hollow stoneware that chips with the slightest ding. LOVE LOVE LOVE these mugs.

Honestly we haven't used the travel mug size versions. We use the vue and k cup normal size.

SO: 2 answers, we just use cold. But in general, with glass (or ceramic) breaking comes from thermal shock. If you warm the mugs first, with hot water (rather than pouring the boiling water in them when they are cold) you will be much less likely to have problems.

Stainless steel is the safest most inert material to use for cooking and the next best material for water bottles to glass. I would certainly choose it as an option over any plastic -- some plastics definitely leech and some have BPA. It's also better to protect your coffee beans from light.

I put mine in the dishwasher for about six months. Just too much work, with all the other non-dishwasher-safe junk to wash. It was perfect but then gradually a screw got loose and the handle got slightly loose and then there was a microscopic leak in the bottom. So I got a new one, don't want to take any chances. It's a drag to have to clean it ( I have big hands and have to put on dishwashing gloves) but it's worth it, since it's such a cool coffee mug. I really do love it. The travel one, unfortunately, has a plastic lip. Not so good....

This is a 16oz travel mug - made of thermal plastic. I know plastic doesn't sound like a quality item, but I absolutely LOVE it. We have 6 of these - and we use them every day. In 3 yrs of use, we have never had a leaky lid, they are diswasher safe and unlike so many travel mugs, the lid doesn't have a lip that's too deep. We have other mugs which have deeper lids and the liquid tends to get away from you. I've never seen this mug in any size other than the 16oz.
