This mug is excellent value for making people “wince”. I drink out of it, and they get all fidgety and grossed out… hahaha. Even though it's only a cup, they freak out because it's a “toilet”! Classic! The only complaint that I have is that it is hollow at the bottom and is NOT recommended for a dishwasher. Also not microwaveable. If washing it in the sink, avoid immersing it fully as the water gets trapped inside the cup – badly designed, but lots of fun.
