The worst money Ive ever spend and we had it tied down. We had 6mph winds. Not only did this happen the 2nd day and all the poles bent but when we were assembling it there was stitching coming out everywhere and was holes in the netting. Very dissapointed in this product. I was hoping with these hard times and the quarentine that my family could atleast enjoy some bug free time outdoors but that never happened. Now i have to pay for something broken
