Top critical review
1 February 2019
I have been using this consistently for 2 weeks and at the start it worked fine. About a week ago I noticed that when I was drinking, there seemed to be air bubbles being sucked up with the water which also makes quite a bit of noise. A slight adjustment of the spout stops this (pushing it backwards towards closing), but there's more of a pull when I drink water. I shouldn't have to adjust the spout to drink properly out of a 2 week old bottle!
