Stops working in less than 3 months

It was easy to install and pair with my Android phone. It worked for a good month and a half. Then the Bluetooth connection started dropping. I had to reset it by temporarily disconnecting the monitor from the battery. He worked one more day and died. They tried several times to drop it, but in vain. Now it has no bluetooth connection at all. Can't debug it as there is no bluetooth for this monitor. Durability is a major concern for these gadgets. At first they worked fine, but after a while…

So far it's working well, great potential.

A device I bought actually works very well. I modified the cables to connect directly to my battery cable by adding an industry standard mating connector for the manufacturer to consider. Finally, if you're keeping an eye on your battery level, there should be a quick way to connect your charger, which is why you're adding a battery monitor in the first place. Makes it very convenient. As this was for an older MX5 model with the battery located above the motor I was able to extend the supplied…
