Well, I received this as a gift from a family member and my husband and I were not excited about it at all. We had seen people using these types of devices out at the zoo/ mall/ park and well it just looked like a mother was trying to walk her dog. Except for the fact that you weren't walking a dog, you were with your child. So we were less than thrilled with this gift. With that being said, I can understand how these could be handy if you were at a very crowded event with lots of kids (Disney World even), and you run a high chance of losing your kid. But I think that at the local zoo or park, it's a bit much. I personally prefer holding my son/daughters hand and keeping a very close eye on her/him over putting a leash on them. The one thing i do like about this particular harness is the cute character on front; at least it makes it more fun for the kids. Overall I just don't like these and am not 100% sure they are safe for kids.
