It arrived, seemed very valuable, I briefly looked at the instructions completely, all parts flushed neatly and dried and then filled a latte. Screwed, flipped over the sink .. it drips. Ok I think, possibly what I've spilled when pouring .. screwed again ... ... wiped screwed ... drip ... screwed back and the ring between lid and cup is again full of coffee. The game I have umpteen times driven until sometime was good. The bad surprise came when I tried to drink out of it. My white shirt is now decorated with plenty of coffee.
After I opened the lock, now coming back to the edge between the lid and cup of coffee out there and you felt pretty stupid if you always first missed a small shower with every sip. Since the shirt was ruined anyway, I did not test 1-2 and it was always the same effect.
I wonder in all seriousness, how to, first get the idea to construct such a thing, and secondly, how to be so bold as a crap even to sell. Either I got a very old version with an extra strong siffenden cover from the depths of the Amazon warehouse, or it really is the purest scrap.
