Reliable Tester With Years of Solid Performance
I’ve always liked this brand and have bought several of their products through Amazon. I use this outlet tester constantly as a quick visual check to confirm our ESD protective mats are properly grounded for sensitive circuit‑chip work. Electricians have told me that older versions of testers like this used to overheat or fail internally, and I remember experiencing that years ago too — but times have definitely changed. This model has been excellent. I’m approaching 5+ years with it, and it’s still working reliably.

Muy buen producto y marca.
Muy buen producto, me ha ayudado mucho a instalaciones eléctricas para hacer comprobaciones rápidas. Lo recomiendo mucho sin problemas, posiblemente lo único malo es que las instrucciones no están en español solo ingles, no tengo problemas para leerlo pero seria bueno tenerlo en español de igual manera.

Simple and easy!
I had bought something that I read some reviews that they were not properly grounded; so I wanted to test the grounds myself…this showed me that the grounds were correct putting my mind at ease! Simple and easy! Works perfectly!
