Has anyone had one of these and what are they like? DS2 had an appointment with wheelchair services this week and they were really negative about them, saying they were really awkward and heavy. I need a double so that ds3 can go in as well. I'm currently using a phil and teds sport but apparantly that doesn't have enough support for DS2 and he needs bilateral support (think that's right) which normal buggies don't have. Can someone tell me they are not that bad? I wish I could try one out before we shell out a small fortune (we have to pay for the difference in price between the single tom cross country stroller and the tandem) on a buggy.
