The light itself seems to be bright enough. However, despite it saying on the package it is compatible with aero seat posts, I wouldn't use this light on an aero seat post. The strap included is not long enough to be used on a deeper teardrop shaped seat post and no special mount is included, just an extra flat rubber pad. My seat post is around 14 cm in circumference and I doubt anything more than 10 cm would work. Now I need to fashion my own velcro strap to make it work on my bike which is honestly disappointing for a back light at this price.

After a ride in the rain, i can see the water inside it and the button broke.

Bin zufrieden. Sehr hell. Laufzeit ok. Ladedauer wie vom Vorredner beschrieben, aber kein Problem über Nacht, oder? Einklinken in den Haltegurt etwas fummelig. Vorsicht, wenn es hier nicht richtig gemacht wird, geht die Lampe unterwegs flöten (ist einem Kumpel passiert). Hier würde ich mir eine schicke, kaum sichtbare zierliche Kunststoffhalterung wünschen.
