Holodeck Timer

Looks like it could beam you up but it's intended for your kitchen rather than the Enterprise.

This very stylish accessory has an ergonomic secret: it requires only one hand to operate.

From the website:

The Gripper Timer grips to the countertop for one–handed operation.

A great timer for multitaskers.

The hourglass shape is designed to evenly distribute downward pressure.

It features a thumb gripper for easy turning, gripper feet for a non-slip grip on your countertop, and short or long tone–set options.

Timer duration: up to 1 hour.

In Titanium/Graphite, White, Blue

or Red.
