used it last night and the round trip route planner is cool.

but i returned it and ordered the bundle version instead. for $100 more, it comes with a hrt sensor, cadence sensor, and spoke mounted speed sensor. while speed sensor seems silly, the hrt and cadence sensor were more than the additional $100. they're necessary for a lot of the 830's training features. the hrt sensor will connect to my forerunner 220 for running as well.

unfortunately they didn't have it in the store so i gotta wait a week.

yes, i imagine something at the local hardware store would be a nicer fix than electrical tape.
