If you are an engine guy, these are perfect !
Perfect for my 18HP Lawn Tractor and even my 8HP mower.
They tell me exactly the running RPM's which allows me to throttle to the
most efficient running speed.

Will it last ?
Works fine. It's durability will be the real test.

Perfect dollar value.
Easy to install being lightweight and not bulky.
