its actually the b******s just spend time with it and to start with buy a palm zire 21 from ebay for about twenty quid and only down load a few days at a time till you get used to it apart from a few slight snags its a good bit of kit
i do about two thousand doors a month
just a few things gets my goat but more to do with me than the system like you go to a door and they say not today thankyou its a hasel to leave them without telling george they are done ,and forget to back it up at pc a few of these a month and your system gets clogged but i back up in paper just in case
but nothing to worry about once you get in tune with it lol at times i need to hot sync my self ,,,its good to know at a glance where you are what your doing and where you need to be tom, and should have been last week just give it the chance this fine bit of kit deserves
and for a one of fifty quid you cant go wrong you could burst your petrol tank and be the same down and have nothing to show for it big thumbs up from me
