I ordered this to use with my Skywalker 15’ trampoline because the poles of our trampoline bend inwards. It fit perfectly!

Pros: 
-It came with adjustable bungee cords that made install (for my 6’ 2” husband) easy. 
- It covers most of the trampoline diameter and, with the middle vent doesn’t make it feel too boxed-in
-It has kept the jump surface cool in the heat of the day (75 degrees direct sunlight so far)
Cons:
-The material is very thin, and I am not confident it will last more than 1 year of weathering.
-In any breeze, the material makes a pretty loud sound as it blows up and down against the bungee cords. Not a deal breaker, but not peaceful either.

Overall, I would purchase again as it extends the usable hours of our trampoline, even if it needs to be replaced every couple of years.
