Bought our Nipper V2 in Nov but have only used it twice as DD was still in pram. The brake (V2) jammed a number of times today - the paddle moved so it was vertical but looking away from you rather than towards you as it does when it's on & working. It then wouldn't budge back at all so we had to manually manoeuvre the metal rods that seem to attach it to the wheels. Total PITA. Love the buggy in every other way - anyone else had any issues?
