just bought it on ebay.. $60 aus so i hope its worth it! Our trips in the car are horrible with DS so i think he'll get good use out of it. looking at it, i think it would be easy to slip my hands under the tray to undo his seatbelt buckle in the case of an accident- it looks as though i could pull him out without having to actually remove the tray. I'll only use it on long trips but i definitely think it'll be work it. I might attach a label/note to the side of it that says it unclips at the back so somebody knows in the event of an accident
