Quality and Convenient
These are easy to install if you have a compatible plug on neutral box. Fits tight. Works perfect. No more searching the wall for the GFCI and looking for the breaker at the same time, it’s always all in once place in the box. Used 4 of these in my garage for 3 years so far and going strong. GFCI tester proves good functionality.
