Hacloser 2 in 1 LED Digital RPM Tachometer Gauge Voltmeter for Auto Motorcycle Car Motor Rotating Speed

Great idea but horrible construction (like every last thing built in China) When they work they do as advertised. Im now going to be ordering my third replacement, I have to because even though these don’t last they are a unique size and I had cut a hole in the instrument panel already. I hope they get better and don’t get discontinued.
