I’ve tried Pavlok, and I can honestly say that it is the worst device ever madeIt’s painful. You have to remember to shock yourself. Device defaults to 10 out of 10 power setting right out of the box. I have no idea why anybody in their right mind would ever pay money for the device.Imagine being electrocuted to wake up from a peaceful slumber… Worst. Device. Ever.http://techcrunch.com/2016/06/06/pavlok-hands-on/
