Query: Disappointed

This product has proved frustrating and it has been returned. The clock and alarm functions were the problem. Even after reading the instructions multiple times and attempting to properly set the alarm to OFF, it would sound at odd times. Any time there is a malfunction with the outdoor remote sensor it has to be reset, brought inside and "connected" to the receiving unit. The 100' range is very "iffy" Unless you have line of sight and little in the way of walls, etc. it may not work. I finally concluded it was more grief than I wanted. Oh yes, the clock never did "self set."Oregon Scientific RMR383HGA-S Wireless Indoor/Outdoor Thermometer with Self-Setting Atomic Clock, Silver
