I got this carrier to serve as a backup for when my other full buckle carrier is in the wash or left in the van. I hadn't tried an onbu before purchasing this. First of all the colors are gorgeous and it is so soft. I love how it looks and feels. After using my other full buckle carrier for almost a year and then getting this I am wondering why I didn't try this first? I love that there is no waist band. It is a little more difficult to put on initially, but that is the only negative thing. This is becoming my go to carrier! My toddler has picked this over my other carrier, so I guess he agrees that this is a fantastic carrier.
