Although i like a lot Rex products, i don´t see much need in this particular product. The real wather products available in the market already do a good job and i can´t see a point in "architect" the weather. Just waste another hour in pre-flight? In the same weather products there are a lot of pre-defined weather situations that you can load in your flight if you want a particular situation. Well, that´s my opinion.
I´m much more interested in the other product, Rex Weather Direct and what REX will do to raise the bar again.
