We now have 4 of these bottles and use them for leisure and work. They are very stable and are not even expired, even if they cross are cycling in a backpack. The drinking spout has an optimal size. The tab to fasten the lid on the bottle is very handy and shows up now (after 2 years of use) and no damage. The mounted on the bottle scale is useful when filling but also only for checking their own liquid consumption.
