Absolutely the BEST customer service

Everyone at Breaker Hunters have been amazing! I ordered 2 breakers and they were able to cut turn around time from 2 weeks to 4 days. After receiving them I realized I ordered the wrong ones and not only did they accept the return they shipped out the ones I needed next day air at no additional charge. Farah is rockstar and they have a customer for life! I can’t thank you enough everyone at Breaker Hunters you guys saved me and our job from being delayed twice!! 10 Stars!

My plant was down and I needed a breaker ASAP after a diligent search we found one. We opted for rush service and our plant was back in operation the next day. Money well spent.
