Very bright but terrible battery life. Charge time is really long too of up to 4 hours. Eventually wouldn't charge after a few months use and the usb socket failed. Don't buy.
Not easy to use and battery life is terrible.
Planning to return the item.
I ride on the street 100% of the time. At night or on gray days the light decreases the likelihood of getting rear-ended.
I love the different options that the product offers. I am seen very well.
The light was of poor quality and initiating the illumination required the depressing a poor quality plastic tab. I felt extremely disappointed.Bike71
