After all the negative reviews we were not sure if we get up there. The assembly instructions are not so easy to understand. The screws have not always been good to push through, but my husband has helped along with a rubber mallet. Then it went. Contrary to other reviews, the frame was easy to close. What's really hard is to stretch the elastic sheet. Here one has to necessarily abide by the instructions and always stretch the opposite springs. Emergency googling the internet and watch a video. That was really extremely difficult even though my husband is very strong. So I would have definitely failed. After just 3 (!) Hours, the trampoline was finite and we are tasting hopped. It springs really great and makes a solid and well-made impression. No initial squealing. The edge cover is nice and thick and I think it's great that the power is being enclosed only at the top. Since no space is lost. Indeed, we have only the little 250cc. My boys (6 + 3) are excited. Now we must wait and see how it so proved itself in practice. Delivery was top by freight carrier with telephone booking and appointment confirmation. High praise for this.
