Breaking bad habits, such as eating fast food, isn't an easy task. But If you're struggling to lose some extra weight or save money, this bracelet will shock you if you eat junk foods.

Amazon is giving you an easy way to cut junk food from your diet by selling a Pavlok bracelet. It will help you refrain from bad behaviors with a few painful zap treatments.

Whether it's spending too much time on the internet, smoking, biting your nails, eating unhealthy, or oversleeping, the bracelet will help you sort your life out.

The Pavlok bracelet will give you a 350-volt electric shock whenever you step out of line or when you do something you aren't supposed to be doing. It serves as a gentle reminder to refrain from bad habits.

The bracelet also has a phone app that can be downloaded on any smartphone.

With the app, you'll have full access to the remote-control feature to conveniently control Pavlok from your phone. You can even set automated electric shocks for different habits.

Your friends can download the app and give you buzz if they catch you reaching out for an extra piece of cake or spending too much time on social media.

According to the manufacturer:

"Pavlok allows you to speak your reptile brain's language by adding an unpleasant element (a safe and harmless 'zap' of electricity on your wrist) to what you have been taught to love (your nasty lingering habit), quickly conditioning your mind to associate an 'unpleasant' feeling with your bad habit... and stopping it altogether."

The inventor also told ABC News:

"It feels like if you were to touch a doorknob after rubbing your socks on the carpet."

"There's real power in using a little bit of pain to help you break your bad habits."

A few shoppers criticized the quality of the gadget. However, many are claiming that it helped them break their bad habits.

One customer reviewed the Pavlok bracelet saying:

"The wrist band is a little awkward, but it does allow for the contacts to be positioned close to your skin for the best results. I've only used the button on the device to administer the shock."

Another says:

"I can't comment on how the hand motion function works. The app is ok and does give some information and videos on how to beat whatever habit you're trying to break. At 100 percent on a decent charge, it is more than enough of a zap to get your attention."

"I'm glad I bought it. So far, I believe it is working. It's not going to cure a lifelong issue in a few days. You have to stick to their plan and really work on it."
