I was very happy with my experience. They were friendly on the phone. They tested/replaced the bad breaker in my main external service panel (without requiring me to be there), called me when they were done to tell me what happened, emailed me the bill, and even make it easy to pay (I used paypal!!). Lifetime warranty too. How easy is that!??!!! I'd use them again for sure.
Pros: responsiveness; quality of service
Cons: none encountered
