Some of the anemometer models that are out there tend to have problems with their balance, their interface with the base, and over a fairly short amount of time, can lose their accuracy. And then, once that happens, you have wind equipment that isn't reliable. Same goes for the wind direction equipment.
Some use potentiometers (like rheostats on a light dimmer) that wear out or wear down relatively quickly. These causes "blind spots" in their accuracy that frustrate an observer who takes both his hobby and his investment very seriously.
Finally...and this happens with even the best equipment, a good ice storm or alternating melting and thawing in winter can find your sensor frozen in one position for days. That is disappointing if the ice storm is followed by a vigorous cold front and winds of 60 mph yet it just sits there frozen.
If you are REALLY serious about a purchase, let me seek out a little consensus from some of the observers I know around the country...and see what they say about the instruments they have.
