The buddy system leash is comfortable for both me and my dog.  I use this for a Jack Russell/Chihuahua mix because she likes to scoot around me as we walk.  She adapted to the different leash configuration very quickly and seems to really like it. The buddy system enables her to move freely as we walk and gives her enough room to roam without being so long that she can get in the street or into other trouble.  The quality is great - the clips are secure so I feel comfortable that she will stay attached to me.  I also like the second clip, which allows me to attach another leash or hook her leash up and out of the way when she is off-leash.  The only thing that I think could make it better would be to add a pouch for my phone, treats or poop bags that I could attach to the second leash clip because the waist band width is a bit wide for the clips of my poop bag holder and my phone holder.
