Leaking shaker cup, pporly designed
This shaker cup always leaks.  I ordered two and threw them both away.  A flimsy rubber o-ring in the cup's lid is supposed to form a seal, but it is very hard to close the lid with the o-ring in place properly, and even then you will still get leaks.  I bought the Tupperware one instead (with the Tupperware, the lid is very tight and hard to get on, but once it is on you will not get leaks).
