I paid a LOT of money for another hands free leash system that was frustratingly poorly designed.  I was so unhappy with that leash, I ended up purchasing this one as a replacement.  This one is simple in design (no water bottle holder, poop bag holder or cell phone holder) but it does a great job of holding what's important-my dog.  It's light weight and compact enough to wear under my old butt bag.  I wish I had bought this one first, I could have saved myself $70 a a lot of frustration!
