Query: Leaks, doesn't keep water cold

This water bottle doesn't have an o-ring in its cap and thus leaks whenever you tip it into your mouth. Also, the insulation doesn't keep water particularly colder than a regular bike bottle. I gave it 2 stars instead of one for not using BPA, but this thing will leave water dribbling onto your shirt and face every time you use it. Works LESS well than a regular water bottle.
