Better than expected

Involvement:General (knows how to use it) - Ownership:1 week to 1 month

Bright light, easily visible from 150 meters.

Cycles through modes in a useful way: blink = warn, red = stop, green = go, and then repeat for the next vehicle.

*DOES* stick to a vertical surface, so you can turn any lamp post into a warning beacon.

Still works after dropping it on a concrete floor.

Hands won't freeze to the stick when it's cold outside :)

Internal LED stick bends after dropping, after that the light is less uniform. (Does not affect its use for signalling, though)

Restarts its cycle when you change the batteries, beginning with OFF. This means you could use it with external power, without the risk of leaving it in the wrong mode; when you restore power, it will always be off.

A fine product.
