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 Simply 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!

I needed to upgrade one of the breakers in my electrical panel and this was the exact thing I needed.
