YIY Electric delivers high quality products at a fair price. Bids include no hidden costs or fees and jobs are completed in a timely manner. YIY employees are professional from start to finish and take great pride in both simple jobs to the most complex. I would highly recommend Cooper Electric to anyone seeking an honest and knowledgeable electrical manufacturer.

My company design Solar system and farm irrigation system. Excellent communication, efficient, professional, reasonably priced, and pleasant to have in my job. I definitely recommend YIY's inverter.

Having worked closely with YIY for a number of years, I appreciate that we have built up a great amount of trust. The communication is very open and honest, we are never surprised by anything. But perhaps most impressive is the lengths to which they go to find creative solutions to our needs.

We appreciate the production capacity your company provided during an extraordinarily busy season which required your services. Your professionalism allowed us to obtain the solution that we required under sometimes extraordinary and unique circumstances.
