We kind of live out the sticks couldn’t find one in our neighborhood so I decided to order it. It did take a little bit longer to get here than what I anticipated but I’m not picky. I was needy. It worked absolutely perfect when we put it in I kind of thought it was a little bit expensive.

For safety and ease of installation, this is the best I've found. Most of my breakers are afci/gfci. I have an old house, and I don't want any problems. Besides, I believe in putting in the best equipment available at the time of installation for the simple reason of not needing to go back over it later in life. Also, even though there are other square d breakers out there, these fit the best.

These were required to pass a home remodel. Fortunately I kept the original standard ones. This trip easily and for no apparent reason. It becomes a nuisance. Passed the inspection and reinstalled the originals and all is good

It’s a breaker… not sure how I can make it sound exciting in a review. My house hasn’t burned down since installing it so I guess you can say it’s great.

I have old knob & tubing wiring with no ground fault protection.This gives added protection with both arc and ground fault.

Received and a questionable item. The breakers received are unlike the breaker in the listing. The markings on these breakers are impossible to read and they are not factory labeled AFCI/GFCI . Completely different configuration of test button. Compared to the GE breakers sold at Lowes and HD, these are suspect. probably better to pay the extra bucks and get the factory labeled item you know is genuine.
