I like this leash a ton - and our previous one broke after 3 years of daily use, so I was happy to replace it. But the new one has a major flaw: the adjustable waist buckle is really uncomfortable :( it’s so sharp at the end of the leash that I’m not sure if I’ll use it for long - might be shopping for another option or trying to find the older model.

Great leash overall. The downside is there is no clean “loop” if you just want to use it like a normal leash. Around the waist option is nice when jogging.

I adopted a new dog from the country but live in a busy downtown area. When he saw a dog friend across a 4 lane street, he lunged unexpectedly. The leash loop slipped off my wrist (I was doing something...maybe putting a glove on/off...and he ran across, thankfully, no cars were coming! I immediately bought this hands-free leash so it won't happen again. I wear it messenger-style over one shoulder. The waist was uncomfortable. I had a hard time figuring out the 6 ways to wear it in the store. Bought a second one but haven't quite figured out how to connect them to have 3 small dogs on one leash without them getting twisted/tangled up. Its very sturdy -- the carabiner type end requires strength to open. Very reflective, washable...I like the blue one.

Quantum 2.0 is the latest product to suffer from "upgrades" that weren't needed but made the product worse. No handle is included, which limits its versatility and kills its usability. The new carabiner is also difficult to attach to collars because of its small size. I could get over that though. The lack of a handle is the dealbreaker. Without that, it is unusable for the most essential reason I bought this leash: walking my pup. BUY THE ORIGINAL while you can. Hopefully Kurgo will course correct for the next version.
