All the best, the goods were delivered faster than predicted. Although has been about 2 weeks time, but when you consider that the goods from the Far East is that's a remarkable speed. On the quality and workmanship can not fault, the temperature sensors are equipped with a neat 3-wire connecting cable (red = VCC, black = GND, yellow = Data). No, there was no guidance in ... I have also read many times in the reviews of other Amazon customers, but honestly I can not speak for any deficiency in the product. It is a common and well-documented on the Internet sensor with a 1-wire current interface, what can one attribute for a manual? The sensor is intended for electronics / hobbyists and who has ordered something to be able to connect it properly. The stainless steel tubes bring a clean heat transfer (I use the 5 probe in my basement on the heating system a) and in addition they are water-tight, the plated shrinkable tubing covers generous cable and sleeve from. Price and goods are top, I can only recommend.
