Have a bad habit you want to break? Amazon will help you out with this shock bracelet!

The Pavlok is a bracelet you can buy for $200 on Amazon. The interesting part? It’s a shock bracelet, and every time you get a craving, you’re supposed to turn on the juice.

Basically every time you step out of line the bracelet will give you a 350 volt electric shock to give you a gentle reminder. And to give you a bit more of an incentive to be good, your friends can download an app which means they can give you a buzz if they catch you eating an extra slice of cake or going on a shopping spree.
