Not even Accusize marked. Generic, not branded. RPM display starts at 0.05, then 0, then dial goes out. Better count your RPMs. Bad design, if You want to check the offsets of your lights, G54 etc. I should have saved a third of the price and bought a cheaper one as I believe they are the same The model doesn't even match the instructions on the box as the instructions are the correct ones Location of the dial for the tachometer shows.. rip off.. oh, did I mention the movement isn't smooth.
