To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
My flip up cap won't close!!! No matter how hard I push. Of course, it leaks when shake it and I can't even hold it closed. I'm REALLY disappointed. I had one of this brand already and it's perfect. There is supposed to be a guarantee. It isn't worth sending it back. That wouldn't be cost effective, I didn't pay shipping to get it here. So, using my experience, you only have a 50% chance of the darn thing working.
Spout does not seal at all and leaks very easily. Even after making sure to forcefully click spout lid all the way down as tight as possible. I can not shake bottle without liquid leaking out all over the place. I can’t pack it or take it anywhere with liquid inside because of leak.
