This is a great water bottle for someone on the go. The lockable lid is great if you are one who puts their bottle on tables and does not want it to spill - great for someone who teaches and has kids running around all day. The button to pop the lid works very well and the spout pours relatively smoothly. Taking the lid apart is a little tricky but nice for cleaning. While the bottle is a good size that holds a lot of water without being unwieldy, it does not fit great in many water bottle holders such as cars; it fits but not as well as you might want which is why it lost a star for me. Overall, a solid water bottle.
