Anchors are good. Unfortunately, the straps do not. ..

Update: As you can read in the comments, kindly the manufacturer support has contacted me. I have taken the opportunity thanks to report the problem with too weak plastic closures. But new closures there is not anyway. Well I have my old not returned because it just romp the autumn storms and I do not know what would make the trampoline without the straps
PS: This still open, of course, if you just hard enough and accuses it have to be a Hulk.

It was here in the other 3 star reviews already mentioned. The anchor holding very firmly in the ground and at 4 piece, a stronger wind will not do anything. The screwing is recommended for moist soil. Then it's much easier than in hard and dry clay. A rod or the like. As lever arm is not required, it went well with the hand. For instructions on how one misses and searches in vain. I had to repeatedly view the pictures in Amazon to understand how the belts must be installed. The straps are only moderately well finished. The seams are typically Chinese. Bad, fast and imprecise. When lashing the snaps of plastic are already up on the voltage. So all left a little looser ...
