Product Description:WMF 06 8666 6790 Stainless Steel Coffee Mug - 0686666790. Stainless Steel Finish
Amazon.com Review:The Germany company WMF works with top European designers to create products for the modern home that innovatively marry style with function. Caroline Shäfer designed this handsome coffee mug for the company's Kult collection. Made from high quality 18/10 stainless steel, the mug features a satin-finish exterior finish in keeping with a contemporary look, while the interior surprises with its mirror shine. The double-walled construction keeps coffee and tea hot without scorching lips, while the black polypropylene handle not only looks cool but stays cool.
Though fingerprints and smudges can show up now and then on stainless steel, a good wipe with a soft cloth should clean them off. The mug is also dishwasher-safe. Measuring four by three inches (excluding handle), the cup holds twelve ounces of coffee or tea. --Ann Bieri

handle detached from mug
Bought two of these in March 2008. They were used once a day and washed by hand. After just four months the handle of one mug detached from the body - they are just glued on. I was willing to pay a premium price for these mugs since my plan was for them to last many years. Would have been better off at the dollar store with mugs that I knew I would have to replace every four months.

Great mug but expensive
it should be .99 mug, but you pay for the nice design, this is what I was expecting before I order it.
it is works great with the coffe warmers, it is actually my main reason to get this .

The best I could find to meet strict criteria.
I wanted a mug that: (1) was insulated, (2) held at least 12 oz., and (3) fit in a Tassimo coffee machine. This met all of the criteria, although there's not any extra room for creamer after the machine makes a 12 oz. cup. Yes, it's expensive for what you get. But it's very stylish and beautifully made. And, considering I could give up the next I will frivolously spend, I'm not going to complain. I will take the other reviewer's test results as evidence of its insulating qualities. But, frankly, if they didn't add some polypropylene between the inner & outer walls, its performance vs. a ceramic mug would be laughable. If you read the reviews and make an informed decision to buy this, you will not be disappointed.
Amendment: After living with this mug for awhile I am reducing my rating to 4 stars. I thought that it's insulating qualities were somewhat suspect and, the other reviewer's exhaustive testing notwithstanding, I am of the opinion that, although "insulated", in reality it has no perceived improvement over a ceramic mug. If it had a lid, it would be better. As it is, if you want your hot liquids to stay that way, this is not the product for you. If you like your coffee hot, be prepared to drink fast.

Definitely worth it (for me)
Sure, it's (at the time of this review) and of course that made me hesitant at first. Realistically, however, for my purposes it really wasn't that bad. I needed a slightly more professional mug for coffee / tea / etc at work and this was perfect for my needs. It's the right size, quality, and style... and it matches the Nissan thermos I also picked up on amazon.
Don't get me wrong, I don't think I'd invest in a whole kitchen's worth of these mugs, but for what I need and the amount of use I get from it, the price isn't a worry. As an added plus, it was eligible for the 4-for-3 promotion.

Hot mug
I got this item so my coffee would not cool down so fast. It works okay for about 1/2 hour but zapping in microwave would be faster but microwave arcs on metal. I enjoy the size and comfort.
