Has anyone tried running with ones of these? I want a jogger because I can't find the time in the evenings to fit in a run longer than half an hour so Id like to be able to go out during the day with DD. It seems to be the cheapest and as money is tight that's appealing, but if its rubbish there's no point me wasting my money. I wont be using it for more than jogging (I use a sling as everything is within walking distance) so id need to know it could cope with being run with 2+ hours a week to help me extend my long jog. Any reviews?
