I've had a positive experience with this light:

I typically ride very early in the morning here in Guam to escape the heat and humidity so I needed a bright light to alert traffic.
This sucker is bright.
I used several review websites that confirmed quality and the fakespot app I use did not detect fake reviews on Amazon that normally plague other light reviews.
