What is StopWatt?

StopWatt is a plug-in electricity device sold for use in the home. The image above and the device photos below come from a StopWatt seller page, so you can recognize the product when you open the offer.

The seller makes claims about electrical performance and lower energy costs. We have not independently tested the device or verified a typical household bill saving. If savings are central to your decision, request independent evidence relevant to homes billed in kilowatt-hours.

Before you choose a package

Check your quantity. Compare one device with any multi-device package the seller currently offers. Confirm what will arrive before you pay.
Check your total. Look at the full checkout amount, including shipping and taxes, rather than relying on a displayed discount.
Read the return instructions. Check the applicable window, any exclusions, and who pays for return shipping. Save the written terms.
Verify performance claims. A plug-in device's light or packaging is not proof of lower household energy consumption.

Worthlume's take: The best next step is to check the seller's actual product details and purchase terms. Do not treat a percentage-saving claim as a result you will necessarily see on your bill.
