The only negative is the Edge doesn't automatically recognize the second one; I have to find it in the sensor menu and manually connect to it.
I was going to say the same thing. Buy 2. Of course that cost more than my bike.
That said I am not impressed by the security of the charging port for external charging.
An electronics insurance policy might pay off with a search for a low profile/magnetic plug, as well.
Same issue of needing a tether attachment point for the varia rear, for those of us with little faith in rubber bands.
