Toothbrush that sends an expiry date notification

With this toothbrush, you do not need to be reminded to change your phone. This innovative digital brush cost just six dollars.

The 90 day brush, is the brain-child of Brush Buddies. It has a timer, an LCD display that reminds you when it’s time to get another brush.

An in-built notification sound will alert you,when the 90 days time-line for using the brush expires.

Gizmodo says the brush’s display has been programmed in such a way, that it will send you daily messages like “Ewww this brush is gross,”  so you can change it.
