I have a Davis Vantage Pro for two years now and find it to be superb. Is second Davis system I've had. First was wired and a bit messy to install etc. Vantage Pro is wireless, works perfectly. Only prob I had w/ it was in Frances last year, when the mast I had it on separated from the side of my house. The machine (sensors, solar pane, anemometer, & rain bucket) crashed to the ground. Broke the rain bucket, which was quickly replaced, but all else continued to work wonderfully (solid state really is) and I was able to track Jeanne after remounting the mast to my boat shed.

Great support from Davis, very helpful on phone, good parts support, etc. Solar panel & wireless work flawlessly. I heartily recommend both this model and Davis in general.
