Many previously established power screwdriver technologies are integrated into the GYRO. The GYRO is meant to be a lightweight, portable and compact tool that can sink its teeth into even the most inaccessible screws in your home. As such, it comes with a light-duty 4-volt Lithium-ion battery pack. Unlike some other rechargeable batteries, you can energize the pack whenever and however you like without worry about battery memory problems.

And the company says the pack will hold its charge for roughly a year and a half, which speaks to the GYRO's purpose of occasional use. There's no battery level indicator whatsoever, though. When the power pack runs low, the device just stops working and an LED blinks a power-hungry distress signal.

In other words, you won't be doing hours of work with this tool. It's meant to help you tighten (or loosen) those sneaky, problematic screws that lurk in every house. To that end, it also has a tiny LED near the business end that illuminates your work area.

Black & Decker throws in two standard screw driving bits with each GYRO. You also receive a two-year warranty that covers any defects.

To use GYRO, you grip differently than most screwdrivers. The pistol-like handle end of GYRO flattens into a smooth, wide surface that settles into the palm of your hand. That big surface is actually one large button, called the motion control activator, and because you'll be pressing into the screw head each time you work, you'll hardly notice it. But unless that activator is depressed, the motor won't work.

In addition to the activator, Black & Decker built in a 45-second shutoff timer. It protects against accidental battery usage in case the motion activator gets jammed against that roll of duct tape in your junk drawer.

Those specs make up the backbone of the GYRO. On the next page, we'll drill down into the details of what makes this device unique to the realm of power tools.
