Review on 🔧 The ROP Shop Black Small Engine Spark UTV ATV Outboard Bike PWC Tachometer: Hour Meter + User Manual by Josel Lambert

This works except RPM measurements are disabled. When idling, the craftsman motor rotates at 4000 rpm. Under load the revs are just over 5000. Yes, I pressed the buttons for the correct functions when actually trying other functions to see what they would do. You read no better. Tried on my small Honda alternator with the same readings. I figured I could still use maintenance hours. Update: September 2016 Downgraded to one star because zero stars is not available! Installed on a pressure washer in July this year. Then it worked, or rather read. I highly doubt my pressure washer was spinning 7000rpm. And yes, it was installed according to the instructions. Went to use yesterday and nothing was read! I pressed buttons to no avail. Guess you get what you pay for. I have two trail meters and both read well. One is older than this one.
