What a perfect Birthday Present for my Child. Arrived very quickly and packed very nice. Was extremely easy and fast to put it together.  It's not shaky, it stays in place, and it's sensitive enough to give my toddler a good bounce. The design of the hold-on bar is proportional to the jumping space so it provides a really fun experience. It puts my toddler's weight in the center so he gets a great bounce, and the bar that he holds on to really keeps him in place even when he twists and swivels. It's lightweight and my toddler moves it around when he's off it. But when he jumps on it, it doesn't budge. Even when I jump, it stays in place. I can’t say enough good things about this little mini trampoline! My toddler absolutely LOVES it!   I’m very happy with it! It’s already provided hours of entertainment!  Assembly took 10 minutes. Much better than other kids versions out there which are more expensive. The quality of the trampoline is excellent and very good value for money.
