Compact clockwork timer that indicates the estimated time required for the smell to dissipate after a trip to the toilet. The yellow dial on top twists through five different ratings depending on the power of the scent. These smell ratings include “All clear”, “Mildly fragrant”, A bit whiffy”, “Give it a while” and Toxic! Do not enter”. Twist the dial to the appropriate setting and it will count down, ringing when the appropriate amount of time has passed.
