Title: Broken Cap
Review: These bottles have a wonderful "patent pending" cap, which consists a toothed base and top separated by a spring. The problem is that the two halves of the cap are joined by plastic butterfly tip, which means that any bump that snaps just one side of the rod will render the cap useless. Now, why brunton decided to patent this mechanism is beyond my understanding, since a monkey could have designed a better mechanism, and why the cap is made so that it can be carried by the cap is ridiculous, since any bump will break it. Either do yourself a favor and get a different bottle, or know that you will have to spend extra money buying a different brand cap.
