Great light - poor switch,
Verified Purchase(What is this?)
This review is from: MetroFlash Danger Zone Tail Light (Misc.)
I cannot quibble at the price I paid, nor the quality of the retina-dissolving illumination, but the switch is such hair-trigger device that I use a bottle top and an elastic band to stop it accidently draining the batteries whilst not on my bike. Be warned – and carry extra batteries.
