Product review (2 stars): Poor temperature/humidity accuracy.
I really wanted to like this Weather Station.  It had all of the features I was looking for.  I ended up sending it back.  I just could not get the temperature to calibrate properly.  I have a couple of very accurate thermomenter/humidistats in the home that I used to calibrate it with and no matter how many times I adjusted the indoor temperature and humidity it just wasn't even close to being accurate.  I found it to be off by as much as 6 degrees in some instances.  I would calibrate it to two indoor temp/humidity guages that were both showing the same temp/humidity.  I placed the WS-11 next to these units long enough for it to settle in.  I then adjusted the unit to the other two units.  Later in the evening the other two units would show 72 degrees in the house and the WS-11 would show 79.  I'd calibrate it again.  Then in the morning the other two would show 72 and the WS-11 would show 68.  I'd keep adjusting it over and over again.  Finally I gave up and just sent it back.

I may have gotten a bad unit.  What good is the device if it isn't even close to being accurate?
