Review on Durable Waterproof Dog Training Leashes - 5 Length Variants for Effective Recall Training of Large, Medium, and Small Dogs by Sung Shorunov

Biotan is great, I like the stitching and the quality there. But clips are a different story. I ordered these leashes in bulk because I needed a more durable carabiner for my dog training clients. Conventional clamps have given me problems in the past. I thought it would be a good option. But I had a lot of complaints, and I myself felt that the clamps came loose during training. Any pressure on the clamp due to the tangled wire will open the clamp slightly. The springs in the clamps have no resistance. Use with caution.
