Lasts a long time on "flash" mode.
Couldn't initially get the " flash" mode to work.

On constant mode it doesn't last my journey to work ( 50 minutes).

London GB Everyday cyclist
Works pretty well and is lightweight.
Not that attractive. And a bit fiddly to turn off and on. E.g. the best lighting effect (basic bright flash) is an awkward combination of buttons away.
