Review on DEWENWILS Outlet Tester: LCD Display, GFCI Receptacles Tester, CAT ll 300V, 7 Visual Indications, Home & Professional Use by Bill Gomez

There are many cheap GFCI circuit testers on the market but I love having the voltage readout right on the tester! I'm a handyman and I replace a lot of GFCI sockets every year, people rarely test them and sometimes they test fine but they don't really work. The presence of a tester for functionality is important, the voltage indicator is just an additional plus. I use this for troubleshooting and to review my work when I'm done. Customers are also impressed because it looks a lot more professional than my old one.
