I have the
WMR-968.
Worked fine for a year or so. Then the wind speed quit working. I thought it was the sensor and/or transmitter on the anemometer at first. Eventually, I did a full reset of the base station and the wind speed worked for about 3-4 hours. I'm guessing something else in the house is interfering with it. Now, 2 of the 3 cups are missing on the anemometer. Not worth the money to replace at oregon scientific prices. occasionally they show up on ebay.
Other minor complaints:
The rain gauge is slightly off when compared to an old fashioned cup type.
The back light on the touch screen can't be set to stay on. You have to touch it to read the screen.
