We purchases the base which comes with satellite monitor. We have the base inside, the other monitor outside and bought a second for our wine cellar. It was easy to set up and use. It is accurate and we haven't had any problems after a year.
Customer Review: Oregon Scientific BAR898HGA
This is a swseet system for monitoring the temperatures in 4 locations. I have the base unit in the study, one outside, one in the basement and one in the attic. The basement unit I use to monitor the humidity, as we have a lot of stuff stored there, and I want to be sure the dehumidifyer is set at the proper level. The attic unit I use to monitor the heat buildup in the summer to determine if I need to put in other cooling devices. The outdoor unit and the study unit have the obvious benefits. The system also maintains a perfect time that is set by the US satellite sytem, and so I adjust all other clocks and watches in the house to match this standard. I also view the base unit from time to time to see what the weather forecast is, but that is not its main use.
