Bought from JE spares 2 months ago. Been in my Bmax4 and B4 but sold both of them. Have removed sticker of one of them as the AMB transponder kept pulling it off as it wqas velcroed to the stickers. Boxes for both. Had extremely little use. Selling as I gone 5 cars to two hence I am getting rid of things bit by bit.
