When you live a very busy life, your week can seem like one long day with several naps in between. However, sometimes you end up making do with just a nap at night when there are meetings to be at, classes to attend, and projects to work on. When you do wake up, there’s a chance you’ll want just a few minutes of extra sleep, or maybe another hour. But who wants to fumble around and set a brand new alarm when you’re still half asleep?

This reason is why the Napper Alarm Clock was invented. It has a regular snooze button for those rare nights you actually get to sleep, and wake up at a decent hour. Although, for the rest of the time, it has a 15, 30, and 60 minute button that will give you perfect intervals of sleep. It will cost you $15, but having it means you don’t have to spend precious minutes of sleep resetting your alarm.
