Review on DEWENWILS Outlet Tester: LCD Display, GFCI Receptacles Tester, CAT ll 300V, 7 Visual Indications, Home & Professional Use by Sam Lee
Good if you don't need accurate voltage readings
OK tester if you don't need accurate voltage readings According to the specification, it can be switched off by 2%. My tests show that the voltage reads around 3-4% or 3 volts constantly in this case. I only paid $10 which is the same price for hassle free. It doesn't cost more. The same tester is sold for more under many other brand names. Everyone will have the same problem. The GFCI test function works flawlessly and consistently.
- Good thing
- So-so
