Bought this for my nephews birthday and it is an awesome addition to the backyard! The oval shape is a must in my opinion, it adds just the right amount of space to not feel like you're going to fly off the edge if you're doing "tricks" with the kids.  Setting up the trampoline was kind of a pain, instructions weren't great, but it's not impossible to figure out and is worth the little bit of cursing and frustration when you get the end result
