Hi Adam, and welcome to the forum. My name is Alan, I live in the UK. I had a WMR100, it was a gift from my wife last Christmas.
Unfortunately, I had a lot of problems with mine. The communication between the console and my computer was very hit-and-miss. I don't run my station 24/7. Some days it would connect, others it wouldn't, which resulted in a complete power-down of the of the console and then a restart.
In the end Oregon Scientific UK got so fed-up with my complaints that they replaced my 100 console with a 200, which means that I am able to use the original sensors. The difference between the two is quite unbelievable. The in-built data logger on the 200 is also very good.
My advice to anyone thinking of buying a WMR100, would be if you can stretch the funds go for the WMR200. You won't regret it.
Alan.
