Excellent for my early morning pre-dawn rides.
I have not tried it yet when it is too dark to see the road.
Mine was ~$20.
I tried a true rural night ride this weekend. Overcast with no moonlight. With all four LEDs on, it lights a good patch of road. I was comfortable up to 15mph.
The problem was that I found it hard to aim properly. For "be seen" mode, I had it mounted inverted so the bumps don't overcome the hinge tension, which causes the light to point straight down. Inverted in darkness it casts light upward so it is in my face when I am on the drops.
I think the solution will be to mount it right side up, aim with a foam wedge and keep the hinge closed with a spot of hot glue.
