- MWMARK W.Verified BuyerReviewingEaton / Cutler-Hammer GHB1020 - 20A 1 Pole Molded Case Circuit BreakerRated 3 out of 5 stars7/21/26Good Product, but Disappointed With the Service
Good product, but I was disappointed with the service. I accidentally placed two separate orders and ended up paying freight on both. I had requested that they combine the orders, and had that been done with the freight waived, it would have saved me money.
Other than that, everything was good. I’m just disappointed that no one communicated this to me.
