Just started using a Bolt. Have 25 rides with it, nothing over 45 miles.

Back light (easy to view, set mine to always on)

What's not to like? Maybe...
No collection of irregularly used instructions, like how to pair with another phone (google it)
Software calorie calculation is >2x KJ record.
Might add LEDs could be brighter for some lighting conditions.
I'd buy one again if it were lost. If not riding with a power meter I'd go with the Mini.
