My 3-year old grandson loves the swing; his did hooked it under a second-level deck as he doesn't yet have playground equipment. He isn't able to pump it himself yet, and I'm not sure that feature will work that well--as the mechanism seems jerky.  But, still a nice swing to push. We put padding under the swing and he also wears his bike helmet in case he falls.

Pros: Was easy to assemble but had to buy additional hardware since it's designed only to hook into existing playground equipment.
Cons: Not sure the self-swinging design will really work.
