    The used breaker arrived quickly and was well packaged. Condition matched the description and it installed without any issues. Saved a lot compared to buying new. Very satisfied with the purchase.

    Get it right

    I ordered a 15 amp three pole breaker, paid for second day air delivery, Superbreaker shipped a 30 amp three pole breaker.

    How hard is it to look at the order put the right breaker in the package and ship it. I guess it must be pretty difficult.
