Cable seems faulty internally, I expected better
Purchased 2 at the start of December. Everything seemed fine at first but one has already started playing up at the probe end and seems to have a bad/faulty wire in the cable relief. I’m a hobby user too and they have barely been used. I now don’t trust the longevity of the other probe.
