The supply, Line worked great, that even though I have only ordered 2 days before my sport and playtime with the Line. The handling and the attaching of the line is super easy if you know how a ratchet works :-). That the Tree Protection are is, is really great. So you can also explain to the children that you should also think about the trees and not unmindful pervades nature towards his sport. The children were all very happy and have made very rapid progress and the Red Line was great. Quite great set. Very recommended further.
