I love ours. We have a KZ, a kettler tipp topp (kind of similar), and a Tripp Trapp. We used a reg. high chair in infancy with DS1 and DD, but got rid of it and went with a TT and baby insert for baby #3. I did not love getting him in and out (his chunky legs were not easy to get in and out of the baby insert), but I liked having him at the table and not cleaning a tray. I sold off the baby seat once he was sitting well and could use the 5 pt harness. He's coming up on 4 and still using the TT. DD and DS1 use our other seats in our office/homeschool room as desk chairs and for handwriting, etc. activities.
