If you've been struggling to save money or to control your cravings for junk foods, perhaps it's time to consider a self-administered electric shock next time you reach for the fries!

A company called Pavlok is now selling a device on Amazon designed to improve your life in many ways. The manufacturer describes this product as a "behavior training device and works by utilizing Aversive Conditioning."

The black bracelet has 150 zaps per charge, which means its battery could last a good few days, depending on how "naughty" you've been.

It's Time To Stop Spending Too Much Money Or Eating Junk Food

Basically, every time you step out of line, the strap gives you a 350-volt electric shock to give you a gentle reminder.

Apparently, your friends can even download an app compatible with the strap. It means they can give you a buzz if they catch you going for an extra slice of cake or a spending spree.

The product's creator explains:

"Aversive conditioning is essentially behavior training that uses negative stimuli (in this case, a small electric shock) and association to help reaffirm a specific action as undesirable."

"The reason so many people continue to smoke even though they know it's bad… is because, for many, smoking IS pleasurable."

"So many people continue to consume unhealthy snack after unhealthy snack because it often DOES taste good."

"And that's why Pavlok is ultimately so effective."

Pavlok Can Also Help You Break Several Other Annoying Habits

The strap can help you control habits like wasting time online, mindless eating, eating fast food, biting your nails, smoking, and oversleeping.

According to the product reviews, this device works best for those who have a problem waking up in the morning.

The way the bracelet works is rather simple. The inventor of this strap compares it to having food poisoning. Once you get it, you stop eating the food that gave you the poisoning, and that's called aversive conditioning.

"Using the slightly uncomfortable stimulus of an electric shock, Pavlok helps train your brain to associate a bad habit with the uncomfortable stimulus. And after as little as a few weeks of associating the two with consistent use, your brain begins to say: 'Hey, wait a second. Maybe I DON'T like smoking.' 'Hey, wait a second, maybe that donut doesn't do much for me at all.'"

And shoppers have mixed reviews. Some critiqued the product's design and quality. Others concluded that it's helpful to break minor "bad" habits.
