5 stars Review of weather link usb data logger
Working perfectly, and very useful for data acquisition that I will use for my biological research. I am enjoying the ability to have precise detail to use for analyzing specific times.

2 stars Davis WeatherLink USB Data Logger
The Data Logger I think is for people who want to keep records, spreadsheets etc. and for that, it is probably great. However, I was wanting a live weather provision for online weather. I probably should have got WeatherLink LIVE.

5 stars This is very interesting.
The data logger provides interface to a PC or I suppose a smart phone for those who are so inclined. I am still learning but the part that impresses me most are the graphs. As I write this my other computer is showing solar radiation and temperature on the same graph. "Very interesting." I am disappointed in the rain graph. It shows the rain in the previous 15 minutes. I would wish for a graph that shows cumulative rainfall like a rain gauge filling up. It is possible that is a feature I haven't found yet. Learning a new piece of software is always a challenge and I enjoy challenges. I would say it was money well spent.

A little difficult to install but with the help of Davis Tech Support got it running in no time. A must have!

5 stars Building my own weather database.
The data logger works great. Davis' software however is dated and needs modernization. For me the benefit of this device is that it enables the creation of a weather database from which I can create my own reports and charts.

5 stars Must have for station to computer data transfer.
I have one of these on my Vantage Pro2 and an older Vantage Vue. I will say I have had no problems and they work flawlessly, easy to install, adequate cord length. You have to have this if you want to transfer data from your station to your computer into the free program Weatherlink. (The program is extremely easy to use and has never failed me in 6 years service.) The logger is supposed to be able to store data for quite some time before you have to download but I download once a week. The only issue I have is I feel the data logger should be included with the weather station. The price is a bit high in my opinion and my guess is most people buying a station have computers as well and want to have that data stored there. But once it's installed it's an integral part of the system and works great. The software is very simple and you can graph any parameter and has a wealth of data. A must have.

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.
