I could not turn the hook in my lawn, and they did not stop! While this could also be due to the nature of the soil (under the grass rather stony) but it was not nearly firmly in the ground. In addition, the straps Waen definitely not to tighten! When correctly assembled, the belts were always to solve by hand. A storm has more power than the hand. However, very good contact with the seller! I got the money swiftly and without hesitation back!
