Hygienic, practical, close

The bottle is completely sealed (with still water, carbonated I did not try).

It is impressively large diameter from her. But that does not bother me.

At the last sip you have to watch not to stain (due to the large opening). But that can be :-)

Me personally disturbs the connection of the bottle to the cover. The plastic band is always somehow in the way. A stitch scissors creates here but quick remedy - the connection can be cut off easily. In my 0.5 l - bottle from the same manufacturer I did the same.

I've been using the bottle at the gym and am very satisfied.
