hi all,just a word of caution,i have fitted the x system,well satisfied,but,after a trip,300 miles or so,the bracket holding the nozzle had disappeared,the adhesive pad had come away from the plastic bracket,not from the frame but the bracket itself,the adhesive pad was still on the frame.i have taken this chance to upgrade to the dual nozzle,again it comes with a stick on pad,all good but for extra security i made a plate which fits in the 2 grooves on the bracket,long enough to secure with cable ties on each end.£25 plus is a lot to chance losing,btw,im not the only one to experience this. happy days ahead
