Faulty Multimeter

I have been using an old cheap multi-meter since 2010.  It has been in the rain, it has been abused, but it was giving plausible readings, so I am still using it.  When I was using it to measure the coil, then it was clear it was not zero-ing.  I thought it was the leads, and it turned out, it is the meter.  I am still debating if I should throw it.
