Visually appealing and fall protection. Has quite a few crashes survived off the table. The closure, however, is not so very inspiring. It often runs out a lot of liquid under the lid. That our little one gets an excessive amount of fluid through the bill, I can not exactly say. Mostly draws with plenty of air. And sometimes you can anstrngen so much as you want and nothing comes out of the beak. Then it's back screws apart and seal readjust etc. can sometimes be really annoying. Too bad.
