Strength:

Cheap, bright, useful settings, USB rechargeable, great battery life, lightweight

Weakness:

Rubber mount is adequate but won't play nicely with smaller diameter tubing like the seat stays on my old 10sp. Had to attach to seatpost which means it sometimes gets nudged by my leg while riding more technical stuff.

Fantastic value and very convenient. Mount could use some work but it's adequate to start with.
