Review: Just installed and works fine. Tach is accurate.
Review: I installed this on 2 motocross bikes to track the engine hours so I can use as a gauge for maintenance. It appears to track accurately. It was easy to install. I just wrapped the wire 5-6 times around the spark plug wire and held it together with the supplied zip ties. I then slid it up the wire far enough so it wouldn't be exposed and couldn't get ripped off. I used 2 zip ties to secure the module to the frame where I could see it. Then cut the remaining wire and used a couple other zip ties to hold it with all the brake cables. Very clean set up. Seems to be made well. We'll see how long it lasts.

Installed on an EU2200i generator and worked perfect from the start. Time in 10th of an hour intervals, and while running shows RPM on the screen for nice information at a quick glance. Really cheap addition to run a maintenance schedule on your small engines on hour usage.
