I have the easy walk and like it.
Every once and a while if I don't tighten the piece that goes in front of her chest, she can wiggle an elbow out and slip out of the harness. I would never leave it on her unattended or with someone who isn't that attentive or knowledgeable about dog behaviour (ahem, my boyfriend's parents).
As with anything, there is no fool proof or dog proof or perfect item. You sometimes need to try a few options and variations to find what works for you (walking with a harness, or perhaps another way to get the dog to walk nicely)
