The sealing of it is a real disappointment. You can't carry it except upright. A simple screw-on plate cap would have prevented any leakage, but they just put a plug. Other than that, it maintains the temperature exactly as I wanted, from home to work, where I make my coffee just fine.

It is a quality product worthy of its name.
It has all the certifications to use it without fear.
It keeps water frozen for 12 hours under almost any conditions and its price is reasonable.
I highly recommend it! !!
