I spoke to the technicians in Derala and it was great working with them. Thomas on extension 114 knows his way around. He even said he would give permission to send the product back but…

I'm clearly not the only one complaining about this. I bought mine a few years ago and had problems with it from the start. Well, it ended up failing completely. I bought this to use with Derale 16825 (https://www.amazon.com/gp/product/B004XONXRQ/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1#customerReviews) which I rated 5 stars a few months ago . , also mentioning problems with the relay/controller. It was unreliable from the start, intermittent operation over the years caused the engine to
