I just received this today and my 4 year old and I took it for a spin to check it out. My son enjoyed wearing it and was pleased to do so, as was I. I feel strongly that it instantly gave us both a sense of security. I love this new product for a mom who would never consider older leash like child safety options. This product has found a great way to take this safety concern and make it more acceptable and comfortable. This will be great to have when we visit busy places.
