Review on Runleader Backlight Hour Meter Tachometer: Maintenance Reminder for Lawn Mower, Tractor, Generator, Marine Outboard, ATV, Motor, Snowmobile & Gas Powered Equipment - Battery Replaceable, User Shutdown by Buddy Colbert

I used to buy this kind of touch from an online retail site - they came from China, worked for about a week, then the internal battery died and I had to throw them away. waste of time and money. I swapped out the carburetor on my snow blower and wanted to set the maximum RPM, so I looked for a tachometer again. When I saw that they had a removable battery, I knew I had to try this. You connect and install like the others. The backlight is a great feature. They came pre-cut with Velco mounting tape so removing the display to change the battery is easy. I cut the test cord very short because it works great where I put it. I will be buying more for my other small motors.
