The interface on this thing sucks The instructions are wrong on how to change it from Celsius to Fahrenheit if you go to the temperature screen and spam the m button until UE-C appears on the screen. Then you can select Fahrenheit and simply wait and it will save figured this might be helpful to someone haha.

After searching all over for a decent 12VDC-powered hour meter and tach, I’d rather go back to the cheap battery-powered ones. This one is impossible to use, and you can’t add time to it, without running the engine, so if you’re replacing an existing hour meter, you just have to remember the time from a previous meter. Save your money, this ain’t it, chief.

I installed this on my water cooled Honda lawn tractor. It does as claimed. Easy to install. Controls are OK but not terribly intuitive. The BIG problem is that I can't see the display with any kind of light around. In direct and even indirect sunlight, I have to cup my hands around it in order to read it. Kinda difficult to do when driving the tractor. I would have given it five stars were it not for this.
