I have three of these from this company! 2 of them are 6 panel and one 8 panel (this one). A+ quality and wonderful with privacy. I have this on my screened in balcony and it withstands the wind pretty well. Fits right behind my giant plant pots. No assembly needed and it was long enough to cover the entire screened area. No more nosy neighbors! Great for Condos! Woohoo!
