We ordered the anchor along with a 430er trampoline. In areas with sandy soils the anchors are much too short to withstand a real storm. With us we could "move" the screwed anchor with relative ease in the ground and then for a real storm hardly an obstacle to represent. I recommend to use in any case, the large, at least 50 cm long anchors or even better to put the same point foundations. I have been through several gardens Trampoline "sail" and see because you should afford more security in view of possible damage to the trampoline and in particular near and far. Conclusion: For solid, hard floors "may" suitable, certainly not for the sand.
