Our verdict

A wearable digital alarm that travels easily and replaces a bedside clock. The listing gives almost no detail on wake strength, battery life or band fit, so it suits buyers willing to accept thin specs.

Overview

A wrist-worn alarm unit with a digital display does the waking here, so the alert stays on your body instead of across the room. A nonstandard battery ships in the box to power it, and the travel form packs easily.

Wearing the alarm puts it on the sleeper instead of on a nightstand, and its travel form packs small. The specs leave out how it alerts, how long the battery lasts and how the band adjusts, so expectations rest on very little data.

Who it's for

Hotel rooms, shared bedrooms and trips are the settings for an alarm worn through the night. Sleepers who need confirmed alert strength, a charging option or a published battery life should choose a model with fuller specs.

Pros and cons

Pros
  • Worn on the body, not a nightstand
  • Battery included in the box
Cons
  • Wake method, battery life and band fit not listed
  • Nonstandard battery may be harder to replace
  • Indoor use only per specs

Performance notes

Waking depends on contact with the wrist and on the alert strength, which the listing does not state. Battery condition drives how reliably it fires night after night, and a nonstandard cell can be harder to find when it runs down.
