Malibu does exactly what I need: it measures inside and outside temperature and the water temperature in the pool, and the humidity in the room. I did not want to deface this by a shapeless, chaotic weather stations with all sorts of unnecessary gimmicks our facility. Therefore, this device is just right: simple, clear, concise and subtly, there is only 1 button on the front to retrieve min / max temperatures and dew point. Inserting the batteries (the display unit last) and it works immediately. My unit is on the dining room window, about 10 meters from the pool thermometer located in direct line of sight. Since there are no transmission problems, as reported by other reviewers. When outdoor thermometer anyway, although I have yet mounted quite far away on the other side of the house. It has a mounting kit that allows you can attach it standing or hanging on the wall. The pool thermometer I have tied with the attached cord on the bathing ladder. It seems to be well made and waterproof and has a large digital display above the water temperature. This device measures reliably what interests me - no more, no less. That's how it should be!
