This is the best alarm clock that I've had. I'm someone who can be extremely delirious when I wake to an alarm, and with previous clocks I've found myself futilely grasping for random buttons while in a barely-awake stupor. That has not happened with this clock; it only has two buttons, the snooze/backlight button and alarm switch. As such, I've found it incredibly easy to switch off in the morning even as my physical and mental faculties are still gradually catching up with reality.
My previous alarm clocks have not just been alarm clocks; they've been radios, simulated sunrises, soothing sounds to wind down the day (e.g. babbling brooks, whistling winds), etc. While these features are certainly nice, my ideal alarm clock is one that tells the time and provides the alarm. There's something especially effective about simplicity that makes this one the standout among all the ones I've owned.
