Product review (2 stars): Not the lid I thought I was getting on the awesome Zulu bottle. Pay attention to which lid you like.
I have a Zulu bottle that I love and I was ordering a second one to leave in the car. Unfortunately this one does not have the lid that my first one does. This lid comes off completely instead of just popping up and out of the way. It requires two hands to remove, whereas my other one is a one hand, quick job to pop open the lid and drink. So beware that this is NOT the pop up lid.
This lid feels wobbly and seems that it would leak, but it does not leak when attached properly. But if you tip it and accidentally bump one of the release buttons (easy to do) it will leak. A lot...not a little!
So be sure that you are getting the ZULU lid that you think you are getting. The bottles are not interchangeable with different lids, so I can't just order the other lid, unfortunately.
