“This is a great product which makes it easier to drink from the bottle however I would have preferred it in a different colour (there are currently only two options).”
“It is a little tricky to use at first as I find you kind of have to squeeze it with your teeth or lips whilst sucking to get the liquid to come out, but once you’ve got it it’s no problem. It also means there is a seal on it without you having to push the little spout down every time (but I would recommend doing this if you are putting it in a bag etc)”
