What Customers Are Saying

Customers overwhelmingly praise this outlet tester for its reliability, accuracy, and ease of use in detecting wiring faults like open grounds and reversed polarity. Most highlight the compact, durable design perfect for toolboxes, and the simple visual indicators that require no technical expertise. Reviewers consistently note it works as intended with no false positives, helping them identify defective outlets safely without shutting off power. Many call it an indispensable tool for DIY projects and home inspections. A few mention the GFCI test button feels overly sensitive, though this minor concern barely impacts overall satisfaction.

Small and easy to carry.

 Would Recommend

Just what I needed for model railroad work. Small and easy to carry. Sometimes I don't need to know the voltage in my layout. I just need to know if the power is there or not. This little meter does it!
