Question: is it vacuum insulated?
Document: Bought this mug for use in the office after two pottery mugs bit the dust. It's light, sturdy, well insulated and looks great. Definitely recommended - haven't taken it camping but sure it would do the trick there, too.
This coffee or tea cup is for the workshop/outdoors. This is insulated and keeps hot or cold. It is cleans up quite well without much spotting. I use this in my workshop because if it gets knocked around it is not going to break. The contact area for the lip has the correct curve and comfort. I recommend this for the workshop worker.
just got my mug and i am loving it...very well made and good looking :-) perfect for my morning coffee... highly recommended and will be getting one for my mom, so you know it past the test if mama is getting one :-)
got it for a friend she loved it keeps coffee warm just what i ordered thanks nice to give some thing you like yourself
While the lightweight of this mug would make it a good choice for backpackers, the roughness of the interior brushed finish makes it undesireable for daily usage especially for beer since the "suds" cling to the horizontal ridges.
We bought this mug because we don't use plastic anymore, but this mug leaves a metal taste in your mouth. I would not buy another one.
Top quality but for me, kind of small. Holds a cup of Joe well, keeps it hot, or keeps me cool aide cold, but really holds about 10 ounces of fluid. If that is what you need, buy it and you will certainly not be let down. Looks nice also. In fact, looks real nice.
This mug is advertised to hold 15 oz's, but just about holds 14, so needless to say we are very disappointed, have burned the boxes before trying to use them, so don't think they can be returned, so we're stuck with them. I was very disappointed when I measured the liquid to put in them only to find they were not 15 oz. P Pratt
This is not a 15 ounce mug. Filled to the brim, only 12.5 ounce with a useable volume of about 11 ounces. Insulating ability will keep your fingers from burning, but will not keep your drink hot very long.
This is clearly not 15 oz. Must be the 12.5 oz version. The mug seems fine but I wanted a bigger one.
Answer: yes
