Review on NKTECH NK-HS2 Inductive Hour Meter For Gas Engine Lawn Mover Marine ATV Motorcycle Boat Snowmobile Dirt Bike Outboard Motor Generator Waterproof Hourmeter (Green) by Daron Ellis

The hour meter is very easy to install and works great. The only reason for 4 stars and not 5 is because I just installed the unit yesterday and I don't know how long it will last. The description says no battery is needed, just wrap the wire around the spark plug wire and insert the other end into the slot on the gauge. Correct and works great. However, the display is on when the device is purchased, so it tells me that there is a non-removable battery inside the epoxy capsule. I just don't know how long this battery will last. The rest of the installation was easy and the device works great.
