From their website:

Conetrol owner, George Miller, died of heart disease on October 17th, 2015. He had been in declining health for the last few years, finding his daily activities more and more difficult to manage. His business had been at a virtual standstill for the last few weeks.

We, his family, understand the strain this has caused Conetrol's customers and friends. We do intend to keep the business going, and will reopen as soon as possible. Please be patient, bear with us, and give us a chance to address your concerns once we get going. We are truly sorry for this inconvenience.

Sorry to hear that.
