So I have purchased and used their products for the last few years and I have been satisfied. However, my recent experience with the company, needless to say, I won't be able to recommend or make future purchase from them. I have a 4200 control unit and the relay is going out. I was told that I must buy a new 4200 control unit to replace the defective part. That is a $500 purchase or a part that is probably $100. That's absurd! If you want reliable equipment, Feniex is not an option!
