I am using it and consider it to be a great product for the money. I bought mine on ebay a few months ago for around $65 but now I see its a $75 or best offer. Unit does everything it says it does and took me about 2 hours to hook up to my f-250. My unit is identical to the 3rd brake unit so I would say they just have a different name on ebay. I use mine with a meter so I can watch o2 sensor variances as I drive down road. It is very simple to ajust to the output you want. Buy it you won't regret it!
