Review on Basic Version Digital Engine Hour Meter for Yamaha Mower, Boat, Ski, Quad, Dirt Bike, Marine, ATV, Motorcycle, Snowmobile, Small Engine, Generator, and Cropper by Kevin Grizzle

This was another product I tried due to the low price but doubted it would work. But it works great. It bounces in the dirt and dust on my lawnmower and accurately measures the hours of use. This is a great product at a very low price. All you have to do is wrap the wire around the spark plug wire and find a place to hang or lay it down. That's all. It constantly displays the number of hours the engine has been running, regardless of whether it is switched on or not.
