One StopWatt device covers up to 1500 square feet. It usually depents on the type of electronic devices that are using your power grid. The older, the more StopWatt devices you would need.

For medium homes we recommend the Pro Saver Pack, containing 3 x StopWatt devices to start with.

StopWatt does not require installation. All you need to do is plug the device into any outlet inside your home. 

It is recommended to spread the devices evenly throughout your home for more energy efficiency.

Once plugged in, your device will light up, and let you know it started working.

Allow up to four weeks for StopWatt to yield noticeable results. During this time, the device systematically enhances your electrical environment, gradually clearing electromagnetic fields (EMFs) and optimizing power quality. This patient approach ensures that the benefits, including reduced power costs and protection against surges, become increasingly apparent for a more efficient and harmonized living space.
