I was a little skeptical about this when I first got it as I thought it might be a bit of a gimmick, and when I saw it I thought it would be too heavy for my pup. We tried it out though, and he has no trouble with it at all. It has two different sized trigger hooks and a number of hoops so you can make the leader longer or shorter, or make loops for holding - so you can use it as a normal lead or you can easily tie it round something without having to take the dog off the lead. You could also use it for two dogs at once (not as a long lead though). It's fabulous for recall training, and we've tested it on the beach, the field, and the woods without getting ourselves in a tangle (yet!).
