Review on GXG-1987 Digital Hour Meter Tachometer Tach Tacho: Reliable Tracking for Yamaha Honda Kawasaki BMW Engines by Andre Noel

it's cheap, value for money. works, but I bought mine last September, and then it worked for a couple of weeks until the fall. Now that I've stripped the mower out after winter, there was moisture in the wheelbarrow and the display was dead. I figured out how to remove the backing, but the battery was welded and glued inside. Why do they claim that the battery is replaceable? Well I guess it is if you're as determined as I am. I carefully pulled out the dead battery without breaking the latches on the circuit board and put in a new battery. I added more silicone glue to hold it in place and now it's working again. I could take it off this fall and leave it here in Michigan for the winter. The Tiny Tach brand I had previously lasted a couple of years with no problems, but it costs about three times as much.
