I have of course removed the protective film on the sucker but I have yet to get the Car Mount Holder to stick onto the windscreen and stay there for a complete journey. During the brief period it remains fixed to the windscreen, the flimsiness of the product allows the TomTom to shake and vibrate whilst driving along, unless on perfect tarmac. This is a pale imitation of the original Car Mount Holder that the TomTom came with and I have had to go back to using the original which I broke, but which still does the job better than this one.
