Baby Reins- Useful or Horrible?

I'm thinking about getting those baby reins/harness for my toddler who loves to zoom around now, off steps and into the street. I always thought they looked terrible, like you were walking a dog, but they are starting to make sense now. However, do they really work, or are they more of a nuisance for the child, who will fight them? You can't just jerk your child back, like you can with a dog on a leash.
