substandard goods

after the delivery postponed twice backwards, finally came the "good part" with us.
There was an installation manual, which is not sufficiently serious in 4 parts and a few screws. In one of the 4 self-locking nuts have lacked the plastic insert, which is to secure the screw. The screws have indefinable heads, a mix of slot and Phillips and are barely palpable, because the head profile is so flat. The strength of the screw is very questionable, one hardly dares to put more than finger tight (and in a ladder!) The surface of the coated steel pipes is unclean, in part, the edges are not coated or chipped. To use permanently outdoors mE unsuitable it is corrosion occur after some time.
Even for the purpose per se, ie as head, this product is not more suitable. It is not a secure attachment to the trampoline possible the curvature of the upper rails is not enough to secure the ladder safely, especially if the ground is a meadow. Just because the ladder from the same manufacturer is, one would expect a better solution for fixing.
Conclusion: cheapest chinaware, not recommended in my view, uncertain and even for this price!
