Have recently this water bottle from Nalgene bought and am more than satisfied. At first I was a little taken aback, because the scale on the bottle only goes to 400 ml, but I have tested it with a measuring cup and it fit exactly 500 ml of pure. The bottle had to unpack a neutral smell, what has not changed after repeated use with different drinks. The Cleaning is totally easy. Either spühlen by hand, takes a moment, or in the dishwasher. Is always very fast, totally clean easily. Would not buy the bottle at any time.
