hello, i'm very happy with the one i bought a month or so ago except for one thing - the brake. it's easy to flip on but sometimes - well, quite often it seems - i have the devil's own job of trying to flip it back up. i don't know if it's me (weedy foot emoticon),a problem with the buggy itself or a design flaw. it's got to the point where i daren't put it on cos i worry about not being able to get it off. i spend weeks and weeks researching buggies before my ds was born a month ago and i never read of any problems with the brakes before. anyone else struggling like this or is it just me??
