We have been extremely happy with our purchase of this larger sized trampoline.  We can easily fit several kids on at a time and they tire themselves out having tons of fun.  As with all trampolines, the net and the pads seem to wear out before the kids. We've had to replace the net, but the trampoline itself is still going strong.

Pros: Larger size means fun for more kids at one time
Cons: Pads and net take a beating
