Review on 🔋 Runleader Digital Hour Meter Tachometer with Maintenance Reminder, Max RPM Recall – Ideal for ZTR Lawn Mower, Tractor, Generator, Marine Outboard, ATV, Jetski, Motorcycles, Snowmobiles, and Gas-Powered Equipment by Jim Booth

Good product but instructions could be better. The connections are a little confusing and I'm not sure how long it will take. It connects to a battery and appears to use an internal battery. The battery cannot be changed, so I think this is a disposable device. Also, programming is a bit tedious. Small buttons and small hard-to-read markings at the very top of the reading are hard to see, especially in the sun. I'm not sure how much I'm going to like it, but I hope that once programmed it will work well and for a long time.
