have two other favorable tried all again returned because completely inaccurate readings. Not so with the Dolmar: robust construction, 9V battery, large LCD display, good description here. I need it to measure firewood a few times per year and it is ideally suited. I have not a professional device for comparison, was therefore carried out ten measurements with wood that I have stored even two years and the excellent fire (Displaying 11-15%) and ten measurements with wood from last winter (15-20% display) and both appear me plausible. Note the instructions for use, amateurish measure on the front side of Scheits brings false readings. Therefore: strong buy recommendation and a lot of fun with this product.
