Title: Good if you use it right
Review: You can't tighten the lid on this, you have to demonstrate some mechanical sympathy and turn it to the closed position. It's not really a screw thread, it's a bayonet fitting. So it only turns so far, like you gas cap but without the torque limiting thing. Treat it right and it seals correctly and works for years. I've been using the 20oz version for around 3 years and it still works perfectly.
