Mixed feelings
Very light weight., the slightest breeze blows them all over so they won't keep the mosquitoes out in that situation.  We put magnets/weights on the bottom to control, had some success with slight breezes.  On a windy night forget it.  They were a bit too long for our pergola so I just cut them off with scissors, no hem and they did not fray, that was great.  I installed them so they over-lap the beam at the top to keep bugs out. Used 3/4 inch electrical conduit pipe and straps to connect them.  Way cheaper then copper pipe.  Okay for the price, order more than you think you need, they work better when they are gathered, don't stretch out real well, they keep gathering back together as the wind blows.
