I'm a contractor in the US, weather dictates what I do day to day, sometimes hour to hour. I have searched forever to find a full screen radar page that loads fast with no clutter and and no ads all over the place. I also use a start page on my browser and this can be embedded into that page and is always current with out a refresh. When I click on the link itself that I have set my area to, it loads right away, no waiting. As for local forcast, I use weather.com, but their radar is horrid and loads slow.
WIndy load time is less that 1 second for every test I have run. They do have some errors that could be sorted but that is for IE, Safari, and a few Android versions.
Imo This is by far the absolute best out there. Granted I mainly use the radar, but I like the fact that I can also see real time lightning strikes and wind direction and speeds.
As far as ease of use, for me it is quite straightforward. The sidebar to set the layers I want to use is a plus. But for others it might be somewhat confusing.
