Hello, i've been using the cover since last fall (2021), and i must say with the flaps down, even with my weith of almost 120kg, 1 heavy child and some bags loaded, you really have to pay attention when there are really heavy side winds in an open field, because obviously it catches a lot of wind...
For me it's ok, i can handle it, counterweight it with my body mass, but i can imagine that for some people this might be very tricky.
But overall i'm super happy with the cover because now even in bad weather my daughter stays dry
