Our trampoline was 5 years without additional security rooted in the garden until it has something Xaver weggefetzt of that 50m landed headfirst on the road. So needed a backup. When you first unpack I thought: what a Boaah packaging! Package, wrapping paper, even a package, bubble wrap, parcel and then: Well pretty lütt! But the extent voted yes in agreement with the item description. The packaging thus rather exaggerated. The plastic Gurtverschlüsse are much more stable than in the picture. On these two points, the manufacturer has so far improved. How long the closures of weather withstand, will yet prove. The little Lütten ground anchors: Since each user probably have to strain himself to use his brain. Depending on soil conditions, the anchor may hardly find grip (dune, rocks) or solid fixed points offer. If you get a spade with the whole leaf in the ground and your jacket can hang that this tipping without, then the ground anchors are well-maintained. If you can tighten without tools these things, or only with the greatest violence, you should look around for other mounting options. Probably for most grass surfaces the ideal Storm Sicherunsset for trampolines. No rollover protection for mechanically much stronger stressed swings or climbing frames. The practical test consists of, perhaps our trampoline'd manage without additional security over the next 5 years or it ends up the next time on a car.
