cabbagechick 1 The cardboard box was very, very difficult to open. Staplers and glue were used so box cannot be opened with damaging it.The parts did not correspond to the manual. The wire was meant to have white marks according to manual but there were no white marks. Also, there were extra parts which manual did not describe how to assemble them.I contacted seller, seller asked me to watch video and I watched it two times however it does not teach how to assemble, just mostly shows a girl jumping on Trampoline. I contacted seller again , no response. I also injured my hand while trying to assemble item.As I wasn't successful to assemble it, the mess of items were in my room for 3 days as seller did not respond quick. I gave up and asked for refund. I was refunded 1000 yen less. Stressful experience so I do not recommend this item.
