Simple install.

Was simple to install and seems to be accurate.

Works well

Works great on my motorized bike. Love that it included Velcro. Super easy install and seems accurate. Also worth noting is this updates the reading every half-second. Most of the other cheap tachs update every second. You'll get a better real time reading with this one.

Works

Easy to install and use

Love this!

I got three of these cool devices. Will be installed on a Honda engine on a lawn mower, Troy-Bilt rear engine TB30 riding mower, and one of my generators. I need to buy another one. These are great since they have replaceable batteries. And they show RPM. You should not really get this one wet if possible. It is waterproof, but not as waterproof as the sealed devices. There is a tiny o-ring gasket in the battery compartment. Be careful it does not fall out. When inserting the battery, there are two prongs, push the battery against them. They will hold it if it is inserted properly. This is the best price for these. Don't pay more! I am going to use EverReady Energizers instead of the included generic 2450 batteries. You can save battery power by holding the M and the S buttons until the displays says off. Then the display turns off and data is saved. The display will turn on when automatically when the engine is started. Here are some pics. I will update this review and add other pics later.

Does what it says!

Using it to tune up junk mowers I've been picking up. No more guessing of RPMs. Easy to use and affordable.
