A standard alarm is often enough to wake most humans, but some people just sleep more deeply than others. For these individuals, the aptly titled SmartShaker 2 is ideal. The thin alarm clock fits comfortably under your pillow and vibrates to wake you. This feature also makes the SmartShaker 2 perfect for those with hearing impairments and couples with different sleep schedules.
Here at the Strategist, we like to think of ourselves as crazy (in the good way) about the stuff we buy (like pillows), but as much as we’d like to, we can’t try everything. Which is why we have People’s Choice, in which we find the best-reviewed (that’s four-to-five-star reviews and lots of ‘em) products and single out the most convincing. While we’ve tried to find the nicest-sounding alarm clocks and ended up with picks for the best alarm clock and a voice-controlled alarm clock, we wanted to see what other ways to wake up were out there. So we found the best alarm clocks on Amazon, according to hyperenthusiastic reviewers. (Note that reviews have been edited for length and clarity.)
