We've got one but I haven't used it for a few weeks. He used to be okay in it and would last 5 minutes or so, but I found the position it put him in would make him vomit quite a bit (he's a happy chucker anyway). If we didn't have that problem I'm sure I'd use it a lot more, but now that he is that bit bigger and almost sitting unaided I find it better to sit him on the floor with pillows around him for when he looses his balance.
