Handy, with good light output. A good attachment clip for using the light on a backpack.

Good battery life and exactly the modes I need: dim steady – dimmer flash – bright steady – bright flash. You can check the battery status with a single press.
The mounting system is simple and quick to use. There is no angle adjustment, so if the seat post has a steep angle relative to the vertical axis, the light points towards the rear tire. This is the case with my mountain bike, though I don't have that problem with my gravel bike.
