I may come across as a salesman for them. That is the ONLY controller we will install. It is such a smooth ride on the hydro's. We are putting in the first traction this year with the smartrise, don't have any experience with the traction yet. On the spot with their delivery times and great after the sale support. What an easy product to install, adjust, and change parameters. The price has always been cheaper to me. When you add in the fact that you use less wires and smaller duct, to us it has been an easy choice.
