Release button very convenient and the 'spout' drinking is very well thought out, one does not turn around.
But before closing remember to wait a few seconds all the liquid returns to his room! Ousinon gard to leaks!
Sealing level, this is not too much trouble condition to target the background, even with the son of the tea bag remains sealed it for me!
Small flat (hence the star less), when cleaning, dishwashing liquid that sneaks into the 'glass' (between what we take in hand and gray container inside) and when it is completed hot water, it leaves everywhere with bubbles which can be VERY annoying if you want to put it in a bag !! The liquid passes between the 'ring' and the black plastic 'glass'.
May be a long rinsing and made him do it well dried it can not be!
Apart from her, cleaning is very easy but beware, do not go in the dishwasher !!!
It's still a product that I recommend for use in the car or at work !!
Moreover it is very nice !!
