TBH we’ve never used a Khyam awning but we did have one of their tents which is more or less the same design less the connecting tunnel. Very good even in really heavy rain and strong wind until it stated leaking at the seams but that was after about 10 years. It was regularly reproofed but no matter what I tried, I couldn’t sort out the leaking seams. In the end, I sold it on eBay for spares or repairs with full disclosure of the problems and got £80 collected!
