Product review (2 stars): Close but no cigar
A nice attempt at a working weather station but the lack of stable sensor readings is making me return it.  The unit has a lot of potential but the seemingly random readings are way off -- even after multiple attempts at calibration.

Pros:  Electronics are stable.  Sensor does work and at range.  Multi-color backlighting is nice touch but isn't all that special.  Lots of data on the display.  Optional display tweaks.  Linear power supply provided.

Cons:  Lots of data on the display.  Sensors are horribly inaccurate.  Calibration seems pointless.  Colors are nice but unless you live in high desert you'll probably just see on color.  Brightness levels are pointless. Very small reading angle on LCD.  Price.

Biggest thing for me was the price point.  If it was half the price then I would probably keep this unit and put it somewhere less critical.  I'm not looking for perfect accuracy but the readings were so wildly off.  Compared to a calibrated unit it wasn't even close -- even after calibrating the WS-11.  A few hours later and the readings were a full degree off.

Decent product but just need refinements.
