Don't get me started on how much this grinds my gears. The annoying "cap flips back while pouring" or making it much easier to screw the cap back on at an angle, not fully closing the bottle and everything spills in the refrigerator if you have to lay it down horizontally. Best solution: just rip it off or if you're not strong enough you can twist it while opened until it comes off. I hope i never run into the guy who thought this was a good idea. I don't think he ever uses a bottle.
