Purchased in 2022 and it never worked correctly. The problem is the tach does not playback your run correctly. The needle jumps all over so you cant get an accurate reading of your shift points or maximum rpm. Sent it back two times same problem it took so long for the repairs that the warrantee expired. Real garbage. Never again.

I ordered the tach in end of June 2018 and didn’t work at all. The light didn’t come on and the rpms were not even accurate at all . I will be sending it back for a warranty claim unfortunately.

The Tachometer works fine. The picture shown included a shift light which I did not receive. I expected the lite to be part of the package. Advise me why the lite was not included. You should send me a lite and change your ad if the lite is not included.
