about a week after I purchase my Handspring Visor I buy the Magellan GPS . my first reaction be `` the instruction for the battery be wrong ? '' as you know , in most aa battery device , there be a spring on one side and a piece of metal on the other . generally you put the flat \/ negative -lrb- - -rrb- end of the battery against the spring and the small knobbed end of the battery against the battery . and in most of these case the battery will be in opposite direction to each other . this be where the GPS be unusual . although the battery do face in different direction , on one the batter negative\/flat side be against the spring , and on the other the spring be against the knobbed -lrb- + -rrb- end . not only be this counter-intuitive , it just look wrong . ok , so even though it be against my better judgment , I put the battery in as direct and it work . however , within one day -lrb- less than 2 hour use -rrb- it freeze my Visor whenever I connect it . I replace the battery and the same thing keep happen . I call tech support and they essentially tell I that `` there be something wrong with the GPS , it act like that when the battery be low '' but I try 3 set of new battery and get the same problem . they say I could return it for a refund and I send it back , only to get a e-mail that be a duplicate of the original shipping order . I think they have receive it and where ship it back to I ? so I call they again and they say that they have a problem with they refund confirmation , but that they do receive my return and I would be credit . another problem - the startup instruction state that the cd-rom include have a online manual - but that be only readable by pc - not for mac . I call tech support and they mail I a print version of the manual . I could not believe that they could not be bother to make a pdf version of the file that could be read by any computer use a free Adobe Acrobat reader . the file be easy enough to identify and load into my pda but I do not find it easy to use -lrb- this be before the manual arrive -rrb- . it be not intuitive and definitely more difficult to use than a map . individually any one of my above-mentioned complaint could have be tolerate -lrb- even send it back for repair\/refund -rrb- but all together I think if I be have these many problem so soon after buy it , how will it be after any length of time ? I have never purchase any other electronic device that have more problem within the first day of purchase . DO NOT BUY - wait until it there be a improve version that store the battery properly -lrb- I suspect that be where the power connection fail -rrb- and that have a better , easier to read -lrb- and universally readable by any machine -rrb- manual .
