Look at this clock.

It’s a clock.
I bought it once because I needed… a clock.
It’s $29, which is totally reasonable for… a clock.
Then it was Daylight Saving Time one day, and I went to update it, but… it was already updated.
That’s because:
The Atomic Time Feature conveniently allows the clock to sync with the WWVB radio transmission from Fort Collins, CO, for accurate time updates.
That’s amazing?
It listens to a radio signal and adjusts itself to the correct time, even during major time changes.
What a kick-ass UX, while seemingly being no more expensive.
Also: you can just put one battery in it to work, or you can put 2 batteries in it, and it’ll work longer, or 3 batteries, and it’ll last over 5 years.
What the what.
Now it just needs to dust itself, and it’ll be the greatest home device ever.
