Review on Versatile 18-Piece Slip Leads Dog Leash Pet Rope: Ideal for Small, Medium, Large Dogs in Neon Green, Orange, Yellow, Blue, Red, and Black by Maurice Ford

Lines are strong, but the rings at the ends of the lines are very weak and cheap. I am a rescue and when we first used them we had 2 dogs that ran away from us when we were taking them for a walk. The rings just unrolled and fell to the ground, rendering the leash useless. Luckily we didn't have a dog fight! In 32 years of rescue work, also as a veterinarian and helping our rescue partners, this has never happened to me! We rely heavily on glide lines for safety reasons. I ordered two packs of these cables and they went straight in the trash! You may have worked with tiny dogs, but it wasn't worth the risk of one volunteer mistaking them and grabbing the wrong leash, causing another to fail. Very disappointed!
