I am so happy with this trampoline.  While the size is a bit small for low impact jogging and other exercise it makes up for that in durability.  Unlike other oval options available in this price range, it has real metal springs that will last, rather than elastic bands that will stretch out quickly. It is sturdy and easy to assemble.  The hand rail is adjustable to a good height but not intrusive to any workout.  

Pros: Sturdy, has metal springs, easy to assemble, has hand rail.
Cons: Small round, rather than oval, limits area of foot placement.
