The material is a little thin, but looks tear resistant, the Abtropflöcher in the middle seem sensible.
The Disadvantages:
Unfortunately, it was saved at the size. My 4.30m - trampoline is quite covered almost. Since you can not fix it with many bands cover, the wind blows the margins, where even recesses for EVT. Rods are high, ie the cover effect and protection of springs is not entirely given. See photos
