Got two holes in my data, each almost 3 weeks long (one last year, and one this year) while sending my VP2 back to Davis.
Originally sent back because the barometer (in the console) would go nuts and jump all over the place, and Weather Display would recognize it was completely erroneous, and record none of the data (rain, temp, etc). Sent it to davis, with description of the problem, and got it back after a couple of weeks. Reinstalled and all seemed OK.
About 7 months later, the same problem. Davis guarantees their refurbish for only 90 days. Called them, and their support people looked up the original work order, and discovered they did nothing to the console, except upgrade the firmware. Got it escalated to a supervisor, and they agreed to again do a refurb without charge. Of course I had to pay to ship to them. They also replace the anemometer unit, though I had not noticed a problem with the wind speed or direction. It has been back for just over 4 months and so far so good.
