Review on Rostra 250 1223 Universal Electronic Control by Born Waheed

Worked on it for 2 weeks with a dozen calls to 2 really good techs and 1 bad one. First of all, the instructions are written overly complex and difficult to understand and after all my time and effort it could be a faulty device causing mine not to work. UPDATE: A replacement has surfaced and via cable only I was able to determine that it worked exactly as it was supposed to, unlike the first. Tech support was adamant that devices never fail, so I installed their $56 speed sensor and spent a lot of time getting it to work. Of course, they can be buggy, which is understandable, but tech support should realize that. They never did, even after a dozen phone calls and all sorts of tests, they just said it was the Amazon sellers fault.
