The U.S. Product Safety Commission has recalled 1.6 million non-contact voltage testers made by Klein Tools, according to a press release from the government agency. Not only can the voltage tester fail to work, it can also be a potential shock hazard.


“The on/off button can remain depressed during the power on or power off cycle, causing the tester to work improperly,” the USPSC said in a statement explaining the recall. “Consumers testing electrical sources could fail to be warned of the presence of live voltage if the tester is not properly operating, posing a shock hazard to the users.”

The over 1.6 million recalled testers were sold between January 2020 and March 2021 at retailers like Home Depot as well as industrial distributors, according to the USPSC. Roughly 67,800 were sold in Canada.

This is why I don’t trust technology. Want to test voltage? Have children.

With enough time and effort, you can estimate exact voltage based on their yelps and cries. Also, their little fingers can get in anywhere.

There are diminishing returns as voltage increases. We still miss Billy.
