    Pleasantly Surprised!

    Items came new, in factory boxes. Well packaged, not damaged.

    Someone cared when the order was picked and packaged that says a lot.

    Thanks

    Got an Eaton "BR" type 2 pole 30A bolt-in GFI breaker. OEM packaging and paperwork inside. Would buy from them again.
