The product is of very good quality but it comes with absolutely no documentation of any kind: user manuals, installation instructions, certificates, written warranty. Had to make my own guesses from internet resources about installation. The ongoing issue with the weather sensor is still not resolved and I am still having guesses (since there are no instructions how to program it) if I received a defective item since support could not provide any proper feedback or expert consultation, even when asked on more than one occasion. So I just gave up. Communication was very good during negotiations for the product and arrangements for shipment. Shipment was organized promptly and efficiently. However, although I did receive some feedback and support when asked, it does not correspond to the value and importance of the purchased product. This type of equipment requires proper user documentation and support. I am not sure that I would make another purchase from the same source.
