Getting the temperature of a coffee, and the sugar / milk ratio just right is no easy matter.
Luckily, the Thomann Travel Coffee Mug does not affect blends in any way at all and consistent results can be achieved every time.
We did try using it for pea soup once, but it was a disaster trying to suck the peas through the small mouthpiece in the lid. A manual would have been helpful, sadly none seems to be available anywhere, even online.
However.. It's still just as good - if not better than - some of the big-name brands that cost 10 times the price. I just wish we'd had something of this quality and price 30 years ago.
But, because of the missing manual, we're giving it 4 and not 5 stars.
