Makes no sense.  This is the most useless item I’ve ever purchased in my life.  This thing is perfect for keeping leaves and debris out of our trampoline, except it’s not for this purpose.  It is also perfect for keeping today’s scorching sun off of the kids while they jump, except the directions tell you not to allow your children to jump in said trampoline while the cover is on.  So so confused.  It’s literally good for nothing.  And!!  You must take it off on windy days!!  I wish I could give a big fat ZERO!
