Review on Lignomat Mini-Ligno E/D Moisture Meter by Will Porter

If you buy one of these in 2021 or later be aware that they contain cheap 9 volt batteries that have been stored for over 2 years and are completely dead. Mine measured 2.3V - the device won't even turn on. They really need to be removed from storage and take out the batteries - soon the batteries inside will leak and destroy the rest of the units in storage. The installation of a spare battery is also not trivial. The circuit board can come loose and aligning the plastic cases isn't easy and feels forced to screw back in, although care is taken to ensure everything is in place and aligned.
