I use this exclusively for road cycling . first the good : it do amazing thing . it track everything faster and more completely than you can with a spreadsheet . there be feature I would like to see but I be hope the improvement can come with future softare and firmware download . the output be better than you can imagine . the graph be really informative . I find myself over analyze my ride . the free -lrb- for now -rrb- link with motion base software allow you to see you ride superimpose onto Google Earth image . wow ! now the bad : the unit freeze up on I third time I use it . none of the reset work so the help line -lrb- only open during business hour -rrb- suggest I let the battery drain . 14 hour later the unit do function correctly . 3 day later the unit lose the ability to find satelite . this time the help desk be no help at all and suggest I either return it or send it for repair . the estimate turn around time to be 10 day . they should handle repair like Verizon and send a new unit fedex and have you return the broken one . Amazon.com do not have the same price so I send it to Garmin for repair . in the meantime I purchase a new one locally and I 'll return it when I receive the repair unit . guess what . 1st day out the hr monitor work only intermitently .
