I've got one and I agree with everything 5inthebed said.
Have had it for three months and I love it ! So, so easy to push and steer, even one handed when holding 2.5 toddlers hand.
Must say though, that I don't really rate the hoods, coverage wise. In the winter, obviously no real problem, but with the sunny days we have been having recently I'm finding it a bit of nightmare for my DD of 13 weeks. Having to resort to the muslin and pegs solution hanging off the hood !Because the back of the seat is open when in newborn position (or covered with a clear plastic window thing)it means the baby is much more exposed - great for fresh air and visibility etc (love being able to look down at her while I walk !), not so good for sunny walks.
Not a big fan of the raincover either, I find it virtually impossible to snap the press studs to the frame - but it still gives good protection, as long as it's not too windy!
Not sure whether the newborn bit is higher than the tandems - a friend has a sport, will try and compare it for you.
The seats also only have three positions. You go from completely flat for newborn to virtually upright with nothing in between. This is beginning to be a problem now DD is a bit more aware of her surroundings and wants to look around. I knew this was only going to be a short term solution (toddler more and more likely to walk) but it is a shame they haven't made the seat recline a bit more versatile, like the newer tandems.
Having said all this,even with these little niggles, I think it is a great buggy and I really love using it.
Sorry for the mammoth post !
