I bought the flexi lead because my rescue dog suddenly becomes deaf if she sees another dog, rabbit or squirrel! With this lead I can take her out onto the beach, or into the woods, and know I'm not going to be spending a stressful afternoon trying to retrieve her. The lead is long enough to let her run, and the tape is a big improvement on the cord that was in my previous extending lead, as it doesn't burn if you get caught up in it! The whole unit is large and heavy, but is also robust. An excellent purchase.
