Well, it was a good unit until it wasn't! After I chased the gremlins out of the Osprey (ie moisture intrusion), it had been an accurate and reliable station. Then during an extended cold snap here in N Texas that included some light freezing rain, the humidity sensor failed. My first thought was a cold solder joint on the sensor board, but once I pulled the unit down and inspected, I found that the WS-2902 unlike the earlier units, used a new IC sensor for both temp and humidity, so nothing to fix. I contacted Ed at Ambient to see if he would sell me the sensor unit but he wanted me to RMA the entire unit. Given that the unit had failed well short of a year into its life, I was disappointed.
So, I revisited my options and finally concluded that despite the cost, the Davis station WAS the way to go. I ordered up the VP2 Plus 6163 station as I wanted all the same sensors as the Ambient station had included. Swallowing the high cost of the Davis as compared to the Ambient units was a challenge, but in the end, I came to the conclusion that I valued the proven, multi-year reliability of the Davis stations over low entry price.
