Exposure Tracer Tail Light?
 

looking for a tail light and this seems good for several reasons:

Small size (i don't have much seat post to work with)

Mount seems secure and easy to take on / off.

CNC aluminum body vs plastic on cheaper units.

Seems very bright and has some side visibility.

USB charging.

Price is higher than a lot of the cheap plastic ones but doesn't seem overly priced.

Would like hear any feedback from those who have this light.
