Reviews from our customers:
“I spoke with Josh Long and he was the most knowledgeable sales rep on transformers I had the pleasure of speaking with during my 2 month long ordeal to find a very specific transformer for my machine from overseas. I really appreciate his expertise on the matter and I look forward to working Josh again.”
Hien Tran“I love this company. I'm an electrical contractor and I use them for all my transformer needs and recommend them wherever I can. Josh Long and Chris Stouffer always return my calls and answer my emails. They provide a great, personalized service. It's nice to go straight to the source to buy rather than going through an electrical supply house or another middle man.”
Naomi Doire“Your service and response was impeccable. The equipment quality is excellent. It was a pleasure to work with Jeremiah. He was fantastic, sent me all the drawings and paperwork superfast. Can't wait to need another transformer. Thank you very much.”
