OK for the price, but ...

For the price of the thermal cup is ok, it keeps you warm and the contents remain safely in the cup and does not run out. Now the big BUT: direct fall out of the box of the cup is the one around the outside really very cheap plastic - but at least around the outside only. When adjusted for acquisitions, the thread of the lid properly and screw on again without it jammed, some practice and finesse is already necessary. In addition, the cup smells very strong at the beginning by plastic, but vanishes after a few times wash.

All in all a fun product for photographers and camera enthusiasts, but who wants to have a quality Thermometers should resort to other products.
