These make drinking from my water bottle so much easier when I'm on the move and prevent water spillages because of the wide neck. I ordered two. One for me and one for my son. The closing mechanism is however quite tight and so I have to semi open the valve on my son's bottle to prevent him using his teeth to open it when at school. It doesn't leak when part opened but I have to remember to do it
Great cap, does what it says on the tin, if you like! I’d like to see a cap with a straw next though!
seems the design is flawed or I have 2 duff ones. when the spout is pulled out you either have to fight against the vacuum or if the spout pulls out further you get a messy mix of air and water.
The change to the pull style cap is a real shame as they are much worse for kids's teeth (and adults if used to open). The nice flip style was the reason for buying the bottle but one of ours had a fault.
Does what it’s supposed to do - what more can you say!
