I was pretty skeptical when I saw these online. I had never heard of the Wacky Walk'r before and was only on this site because a friend told me about the Wunderball. I read about them a little bit, figured that even if they didn't live up to the hype I still liked the second handle close to the collar for added control. Well....I just used them tonight and I LOVED them! I have never walked my 3 dogs with so much ease! I used the coupler on two of them and the plain walk'r on the third dog. Very impressed! Recommending to my friends with pullers!
