Got this for my daughter's house that had an arc fault quit working. It was for a 20 amp circuit that only had the kitchen disposal on it. I expected it to be ground fault (wet location) not arc fault, but I replaced what was there. It isn't just Amazon or this seller, all of these arc fault type breakers are extremely expensive for what they are. I know they must have small processing circuit board of some kind inside but it seems too high. I think GFIs were expensive at first but a website I saw said arc fault was required starting in 2002 which is 18 years ago. To me that's plenty of time for the market to settle down. A similar one at my local box store was $3 more and I could have gotten it right then but they were out of stock. Amazon had it with free next day delivery. I have bought stuff from Amazon with next day delivery that more times than not wasn't delivered next day, This arrived next day, at 8:30 PM. It snapped in perfectly, but that is to be expected if you buy the same brand name. Over all satisfied, just can't justify spending over $60 for a breaker.
