The brief
The first prototype had a blue LED panel. It looked great in photos and terrible at 2am. The final Pulse uses a curved VA LCD with a warm-white backlight and five dimming levels, so it disappears into a dark room instead of defining it.
Sleep first
Press and hold the dim button and the display goes fully dark while alarms stay armed. Tap anywhere on top to bring the time back for five seconds. It is the feature customers mention most, and it costs us about four cents.

I’ve returned three alarm clocks because of the brightness. This one at level 1 is genuinely dim, and blackout mode is completely dark. Alarm is loud but not jarring. Buttons take a day to learn.
No app, no Wi-Fi, no nonsense. Set the time in 20 seconds. The display is easy to read without glasses. Would be five stars with a slightly longer USB cable.
Bought two for guest rooms. They look more expensive than they are and the matte finish doesn’t collect fingerprints. Snooze button is on top and easy to find in the dark.
I only wanted an alarm that doesn’t go off on Saturday. This does that without a phone. Battery backup worked during a two-hour outage last week.
Questions
The questions our support team answers most about this product.
The clock keeps time and the alarm will sound on battery backup, but the display stays off and the alarm volume is reduced. It is designed as a power-cut backup, not a primary supply.
About 2 nits — roughly the brightness of a standby light. In a dark room you can see the time from 30cm without it lighting the wall.
It ramps from 65dB to 85dB over 30 seconds. That is comparable to a phone alarm at full volume, without the phone in the bedroom.
