small, handy, valent device

The use of the device is a flash, then you have to make (except for battery change) never what. Press button, measuring heads stand out in the wood, measure and read.
Messreading is within 0.1 seconds (ie immediately) and there seems to be exactly, I measured my dry wood and compared with the measurement of the chimney sweep = equality and had determined the better unit looked, at least from expensive.
The only drawback: watch batteries are in the unit, which are harmful to the environment on the one hand, tempt you to throw in the household waste and changing is not exactly cheap.
The housing is made of plastic, not looks cheap, is well made and seems to hold.

So make device ready (real program choose wood is pre-set and the wood - symbol visible), press metal spikes into the wood, press the middle button, read, done.
The unit switches itself off after a few seconds sici.

Suggestion: Any make the device a tiny bigger, so you (AAA) could operate it with a small battery.

Overall: thumbs up, did not regret the purchase.
