There’s a reason people are calling this tiny bedside device the “ultimate sleep hack.” The Hatch Restore 3 was designed to help users build healthier bedtime routines, whether they’re new parents trying to reclaim their sleep or workaholics who struggle to unwind at night. With over 6,000 purchases in the past month and thousands of rave reviews, it’s clear that it’s doing the trick for many sleepers. Still, it’s reasonable for anyone to be skeptical about spending over $150 on an alarm clock.
