After a short time the Sichheitsnetz was defective although the trampoline has been used exclusively by our boys 10 and 12 years old. Neither of them weighs more than 40 kg. After some friction with the dealer for a replacement Netzt was delivered. In the winter we have reduced the trampoline and stored in the basement. After building 3 weeks ago then tore a spring retainer to the jumping mat. this is of course not replace. We were told how to prove that the damage already existed from the beginning. So is the law. Well, that we can not, of course. Case Someone who reads a corresponding appraiser please report knowledge - !!! We had some fun with goods and merchants, and can only advise against the purchase.
