This product is FANTASTIC! Easy to use and has made going out of the house so much more easier. It fits great in our diaper bag. It's great to use when going out to eat instead of having to use the dirty and gross high chairs at the restaurants. We've also use it at my mother's house when feeding him lunch or dinner. It just hooks to the chair without any slipping. We had received a different brand as a gift and it wasn't as secure and our child would slip all over the chair. No slipping with this one! Definitely a must buy!!!
