Antwort vom Sport-Thieme Team:
The advantage of the item is its lightness indeed. (Alternatives are usually much heavier and made of metal.) The item is made for outdoor use; but an additional weighting (with ususal ground anchors) is recommended in strong winds. We are sorry to hear that the item was delivered with a transport damage and that it could not convince you in general. We will contact you directly in order to arrange the return.
