  • Nice product but be careful when hooking up the ground probe!!!! I reversed the black and grey wires when plugging in and put 5 volts on the ground. The unit does not work now. Back to the manufacture for fixing.
    I feel this is a major design flaw and should have better pin protection features.
    Still a nice product when working!

No public wish lists :(
