He also holds reliably sealed, and still you can the cup good reopen, even if it was solid turned off. Many Isolierbechern I've turned my calluses in the Handinnnenflächen to the aufzubekommen the twisted end of my cup again.
This mug I get on always pretty fast.
Through the non-slip bottom of the cup is very safe, while drinking it fits comfortably in your hand, and the opening QuickPress I also find convenient. Just that you can drink out of it completely.
The fact that it can be quickly and easily completely dismantled into its individual parts, it is also easy to clean - even in the dishwasher.
The insulating properties, which I still find fine, but not above average:
For example, if all pouring hot water for tea in the cup and closes it, the cup is within a short time outside very warm (what with cold hands and certainly has its advantages ;-)). But all the heat that goes to the outside, does not remain inside. Forever holding the cup so not hot, and given two hours holding the cup the drink certainly not on a hot serving temperature. After an hour, the drink is really only just so warm.
Very suitable I find the cup for a summer on the go to keep a drink for a long time cool - for this situation but are then 360 ml almost back to little volume, on the other hand, a hot drink like tea or coffee slowly to drink over a longer period without it cools the same as in a cup.
Unsuitable However, it is for example, in the morning to make a cup of tea and then nice hot drink in the morning in the office.
For my claims of Travel Mug Fun is perfectly adequate, but for a thermo isolated he simply not perfect.
