I've just been given a Maclaren Techno XT buggy by a family member but it doesn't have a footmuff with it - is it worth forking out for the proper Maclaren footmuff to match or is a John Lewis one just as good? I've had a bad experience with a universal footmuff before which slipped down every time I put my LO in the buggy and made the straps really tight, so wanted to know if having the Maclaren one rather than the JL one makes any difference to this? Thanks! x
