Looks good, but inaccurate and not supported, March 12, 2009
This product includes three weather instrument packages: anemometer/wind direction vane, temperature/humidity, and rainfall, all wirelessly linked to a large LCD display. It shows those data on the display roughly in real time (seems to update every five/seven seconds or so) and keeps track not only of maxima and minima on most of those statistics but also when they occurred... very nice. Fairly easy to set up, see my review on the National Geographic weather station on how to get their similar wind and temperature packages set up. That's the good news.
The bad news is that the system is grossly inaccurate. The wind speed data always reports wind speeds thirty to fifty percent below their actual values (when compared to a NOAA instrument package very near my house), and temperatures that vary wildly as the day goes on.
I gathered enough data on wind and temperature readings several times/day for several days to see that while the AVERAGE value of the temperature reported over the day is fairly close to the NOAA data, the standard deviation is about 250 percent that of the NOAA data, despite my locating the thermometer off the ground and in the shade. The wind speed data's always significantly under actual wind speed -- the cheaper National Geographic unit with its anemometer sitting within a few feet of the Lacrosse anemometer tracked with the NOAA data very well -- despite the fact that I actually purchased a replacement anemometer unit from Lacrosse. (Both units showed the same biases -- wind direction was correct, wind speed under-reported.) Atmospheric pressure was, however, dead on... once calibrated. So, I thought, maybe there's a calibration procedure for the wind speed?
The true insult, however, was when I contacted Lacrosse looking for some guidance... could they recommend better infrared shielding for the temperature gauge? Was there a way to calibrate and adjust the package's interpretation of the wind speed information? Their Web site warned that they were very busy this time of year so I thought I'd be a nice guy and use their email. No answer for two weeks, so I politely asked a second time; no answer. It's been four weeks and I'm still waiting.
This unit seems basically well-thought-out, save for the lack of calibration opportunities. Without that calibration, though, it's completely worthless. Save your money.

I'm a gardener., July 7, 2009
I like to know what the conditions are outside and this is my second LaCrosse. The wind or rain sensor died on my first one and it was cheaper to buy the whole package. It is a nice looking display which you can put anywhere without looking geeky. It gives you all kinds of information, my concerns are rainfall amounts, temperature and barometeric pressure changes. It also maintains a history that you can look back on and a min/max function that is useful. In the winter I am especially mindful of the windchill which it also displays. My first one lasted 5 years and worked flawlessly all that time. This is a good buy.

LaCrosse Professional Weather Station, November 24, 2009
This unit is fairly easy to install and get working. I have several La Crosse weather products and have been very pleased with them. The Aerometer has to be mounted on a mast, I used an eight foot (2.5 M) length of dowel and it works well enough. It should really be on a 10 meter pole but I like the lower one as it gives the windspeed on the deck at the back of the house. The rain guage works well and I have it measuring in mm. It recordes every half mm of rainfall and is easy to reset to zero. Some of the functions settings are a bit complex and the manual should be kept on hand as the procedures are easily forgotten, especially if not used that often. The outdoor temp and humidity work well. The cords attached to the rain guage and aerometer plug into the temp and humidity units and that is where the batteries live as well. The cords are quite long and I have stuffed the left over cords into a tube attached to the deck rail. I would suggest using only one screw to attach that temp and humidity unit as it will be necessary to rotate it to replace the batteries.
A good well made unit that does what is supposed to.
