Rating: - Zyliss Bottle Stopper
Best Bottle Stopper I found, makes a seal tight enough to keep Carbonation in Perrier Sparkling Water bottle for days.
Rating: - Pretty darned good for the money
I recently purchased 4 of these stoppers to replace a well used one tht was given to me. While one of my new replacements showed the same problem as "smigar's" review, I found that a little attention to closing the lever properly alleviated the problem (for that stopper). I have had no problems at all with the other 3 new ones. (Could this be a minor quality control issue?)

This thing won't stay in the bottle. I have some of the previous design and they work wonderfully. zyliss changed the top to be flat and the engineering of the lever center of force, and now they don't work right. These are constantly popping out of the bottle and flying across the room. Good for one laugh but very useless.
