i used to be with ninja tracking until they ceased trading .which left me with a unuseable device.online i found eyetek who use the same tracker.phoned them up went in set me up on the same day.even showed me how to use the tracker platform.staff could not be any more helpful especially the lady in the office.wide range of products.tracker very accurate and credits very easy to top up.for me it is the best small and accurate tracker on the market with full back up from eyetek. philip crossland
