“We ordered an FPLC from GMI. The customer service was excellent through the entire process of customizing the equipment, ordering and the installation. They were very patient and answered all questions in a timely manner. The installation was fantastic, as the company representative put the entire FPLC together and then spent time going over all the parts and functionality. I would definitely purchase from this company again.”
