great idea and form factor let down by miserable online experience , weak user interface and poor service feature . specifically , as note by other reviewer , Garmin 's online service be more frequently down than available - consequently the ability to track you precious item\/pet be meaningless as you be unable to query the system more than , by my estimate , 20 % of the time -lrb- I have be flagging this to Garmin for the past 5 day but who , for the time be , deny that there be any issue with they service availability -rrb- . the track history be only available for 24 hour unless you buy a higher-level package - combine this with the fact that you can not actually access the history for more than a fraction of when you need , you might as well not bother . there be multiple other gp tracking system -lrb- eg the spot  SPOT Satellite GPS Messenger unit  and quality -lrb- better gp recognition and reporting -rrb- . I will be return my Garmin GTU 10 to the shop at the weekend as I have simply have enough of waste my time try to get Garmin to recognize they be disappointing customer .
