s the performance per square meter up to high end standards? Nope. But this does not mean that my Radsail isn't worth every penny that I paid for it. And speaking of pennies, I can have a 1.8m, a 3.0m, and a 5.0m Radsail (all three) in the back of my Jeep for about the same coin as a 4.0m Blade. To me that spells VALUE. Totally agree i have the 3m and still my go to kite i love it.
