We just installed a lightning cool on our Fadal. Looks like it is worth the money ($5,000 factory installed). The service manager from VMC Technologies (Detroit area Fadal dealer) tells me this is an awesome upgrade.
We had ours installed on April 15th. It works so far. Time will tell as to the reliability of this system. I have heard nothing but positive things about this. The Dueblin union used to seal the system is a reliable design. I am going to post after we have some miles on it.
Still working in the "D".
