I have bought this item back in Feb. Changed the top cap about mid March so kids can start using the trampoline due to the nice weather. But the changed top cap snapped last week! Only got about 3 weeks of use out of it and now I have to buy another one?! I have had the trampoline for 2 years before the cap broke and now it took 3weeks and it’s broken again. When I received the item it seemed ok, so I don’t understand how it snapped after such a short time?
