Since I have so few of Trotec from the heater, moisture meter, this time came only this brand as an inexpensive, proven quality questioning. My 6 year "old" Salutron has already made the gretsche and was more expensive. As this product behaves over time to be seen, but a review immediately after purchase is in measuring instruments eh nonsense. But it's in the trunk, solid built and the most important, it measures exactly.
