“I just wanted to take a moment and recognize the incredible effort and outstanding service that we received from CCI recently. In part, the sales team helped us enter our order quickly, but the true testament to your production team is building a 500Amp Fusion and shipping it in under a week!
The customer was in dire need of an SCR with production at a near standstill. We received the order on a Tuesday and CCi was able to have the SCR arriving by the next Monday! (our previous manufacturer would have taken 6-8 weeks!) We are somewhat new to CCI, but not to SCR’s and the fact that the production team was able to complete not only this order but also smaller MicroFUSIONs recently in such a timely manner is not something we take for granted.
Thank you all very much for your outstanding customer service, technical support and in particular the amazing production team that built these SCRs!”
