I am very satisfied with this product. Looks very well built and the optional bracket is good quality with stainless steel hex head screws. I went to the site to check the connection and found a chart (color chart) there that contradicted the instructions I was given with the stats. I called Deral in California and in fact he told me the connection on the instructions page was wrong and the connection on the website was correct. I'm glad I checked. He told me he would report the discrepancy for a change. Update: In mid-June, Arizona stats were working as intended. It shifts at around 180-183 degrees, dropping to around 145 in around 90 seconds while driving. So I can't get enough of this device. After the move, he remained under 185.
