Counter display works great sensor was dead on arrival
This is a pretty good counter. The display is large and bright and it works well on my exercise machine. The only drawback is that it is designed for mounting in a flat panel with the proper size rectangular cutout. I had to use tie wraps, tape and foam backing to mount it to the exerciser. Plus, you have to be somewhat handy to splice the wires and use an appropriate power source. I used an unregulated 120VAC to 12VDC adapter I had lying around.The diagram is clear to me, but I am an electronics technician. Be careful of the power supply polarity.
