I have a GHL doser 2 stand alone unit I bought and decided to go a different route with my build. I bought it as new never used and I have also never used it. The tubes on pumps look like no fluids have been through them and the connection tips are still in the package. I have had this unit for about 6 months as I was collecting what I thought I was going to use for my build. If you have any questions please feel free to ask. It comes with unit, power cable’s, usb link cable, and connecting tips. I’m asking $290 shipped obo.
