We have one at my work-place; a police station dispatch center. Unfortunately we have had numerous problems. First of which is rainfall rates are erratic...totals are way out of sync...for example every time a hundredth of an inch of rain falls, it shows as .25", and doubles itseff over and over...We were advised that it is caused by radio interference. Wind speed occasionally cuts out, and I noticed last weekend, after a major snowstorm the temperatures were 10 degrees low. I figured maybe snow blew inside the sensor and finally melted, as a couple days later the tmps seemed normal.
I hate to diminish a locally-made product manufactured in next town over, Bar Harbor, Maine; but have been disapointed. Also had an earlier version MK1 at my house which had to have wind sensor replaced after only a year. And it also, was subject to erratic rainfall readings; which they also attricuted to radio interference.
I replaced mine with the original Vantage Pro...it has lasted 6 years..and I'm disappointed in it too, as it has had two anemometer transmitter replacements, and one replacement for the temp/rain gauge combo. I would have expected longer life from it. Debating whether to replace it with a VP2.
