I sent him my perfect working ss sending unit to get a return line to get a ss return put in it cost me 9 dollars to send it to him . he said he would call me before any work was done with a estimate well he calls me and says its done and it cost 160.00 and he said he replaced the part where the push on wire goes . so he sends it back to me and charges me 40 bucks and then he fill out the paperwork wrong so there is a 40.00 $ border fee . so when I get the unit it has the wrong wire hookup so he tells me to just cut my new wire end and put a different end on it . so before cutting anything I thought I would test it first and it dosent even work and he wont do a thing for me or stand behind his work. I have nothing more to say.
