I have planned for my robomower a workspace extension in order to occupy it and to relax. I had green hook from another manufacturer. This looked plenty far from the earth and made for occasional Holperer my Mähman. These are a little shorter, but can be hit even with a hammer into the ground. Only direct contact ensures stone breakage. The hooks are almost erdbodengleich and barefoot barely perceptible. I recommend this wholeheartedly with 5 stars
