5 stars Weather Link
The weather link was received in good condition. I had some difficulty with the downloading of the software. I called technical support and the tech person was very helpful. He helped me download and install the software and complete the installation. When he completed the process everything was working properly and connected to the internet.

3 stars Needs an upgrade.
The software works OK even though I had trouble getting the USB interface to connect to my Windows 10 system. I finally got the comm to work by using the USB to Serial interface and testing each comm port to see which one I was on (Comm3). The GUI could use an upgrade (Win 95 long gone). And I have not figured out how to get a direct solar Langleys reading, I just have to interpret the readings off the graph. It would be nice to mouse over a point on a graph and get a direct reading. No way to get Langleys to a printed report that I have found so far.

Weather Shack referred me to Davis for a solution. Tech person was to say the least very abrupt and not very helpful so I hung up. Found my own way to the software set up through a computer tech friend and now installed. Software itself is just fine for Wx history recording. No problems

5 stars New weather system program
Took it out of the box, read the instructions and did the procedure as instructed and the program worked great with a short learning time. Hookup to the computer was easy also.
