Good product that meets the expectations. Strengths: efficient radio link even through a thick stone walls, easy to memorize programming, high accuracy of temperature measurement of the transmitter. Cons: not really transmitter design (art deco 50s, matches the photo), son of branching very short receiver (50 cm?) It is easier to shorten as lengthen :-) display that could be in color and / or backlit at least intermittently.
