Gadget for photographers

It is processed for the top price-performance ratio and holds tight, even if I by solid spinnig briefly problems had the cover (so to speak, the lens of the lens) with a screwdriver. However, this should work easier after some use, but I would take him (as each cup) not simply throw headlong with in a backpack. An upright transport position is already mounted, then everything will definitely be nice and dry.

After the inner metal is warmed again by the warm drink it keeps you warm.
Especially tea tastes like it should, but pure water gets a slight bitter aftertaste (coffee not yet tested).

You will receive this 'objective' in a matching bag that already strongly resembles that of a real objective in appearance.
Not later than the printed one notices, however, that it is not real. However, still a hit at the office.

Unfortunately, the cup has no moving parts, in retrospect, I find, however, that this would only be disturbed while drinking.
All in all a super cup.
