I have bought two of these screens over the years and just love it! I don't have the room for a gazebo so this works great. I too do not fill the bladder with water. I got tired of having to open and close the zipper whenever going in and out of the enclosure. I modified the zippered opening with a magnetic mesh screen closure that you can purchase for your door. This works like a charm and is hassle free when bringing items in and out and your hands are full. I wish the company making the netting thought of this.
I purchased this for over our market umbrella. FINALLY we can enjoy sitting outside without-dousing ourselves with bug spray. Keeps out the flies and wasps also. Comes with screen patch also in case of a small rip.....Great invention at a fair price!!
We have purchased several of these over the years and several friends have also purchased this when they saw ours. Great if you do not have the room to purchase a gazebo... We have ours on our deck over the umbrella - our market umbrella is a 9' and we have had 8 people around our patio table (round) and still have room to expand the screen. Still works great even if the bottom is not completely full of water.
