Cup is tight! all good.

The thermo cup holds tight! This was in itself very important to me.
It fits in 20cl, corresponding with me for a little coffee. The liquid stays hot for about an hour (which is now subjectively, I drink coffee like hot not lukewarm) therefore only an hour.
The time is quite enough to drink for me to alll.
You can put it on and make it with one hand.
He has already several times unscathed the dishwasher.

From me 5 stars, I have nothing to complain about.
