    Fast shipping, everything was fine.

    Not new

    I ordered new breakers and the invoice states that. However, the ones I received were all used.

    Hi Ali,

    Thanks for sending. Can you please check the brackets at the top of the breaker and they if they have markings? If those have been used, you'll see circular scratch marks on the metal brackets and that way you'll know for sure whether they've been installed or not.

    Either way, if you prefer, reach out to support with your order number, they can send you replacements right away.

    I'm really sorry for any inconvenience this has caused.

    Very good price!

    Very good price and outstanding service/communication, I will recommend and shop there again!

    Great purchase experience, shipping and support!

    Needed a pretty rare breaker and found it here. Ordered on line and got the item in two days. Follow up - the breaker failed after 6 months, so I bought a second one. Then I reported the problem so the manufacturer; they said call the seller. Now note that at this point, I have purchased two breakers as I needed the replacement and didn't want to screw around with warranty claims, etc. Breaker showed up at my house, and I reported the failure to Canada Breakers. I HAD A REFUND WITHIN AN HOUR for the second breaker I had purchased. Recognize that they were within their rights to just replace the breaker (so I would have had 2 of them). You never know who you will be dealing with in an online purchase, but these guys rock!
