I'm not using this for pitch black rides, but rather early morning sun just below the horizon efforts. This unit provides just enough light and helps make sure people see me. I'm able to mount this on a variety of handlebars, use the flashing mode with is very bright, get plenty of life out the battery, and it's the right size that is doesn't get in the way of cycling computers, bells, etc. I've even mounted in on a fork of one bike. Charges quickly too. I'm very happy with this product and even bought one for a friend.
The majority of my week day rides are around 2 hours but even with a full charge the light stops working after approximately 1 hour. So for me the light has a very limited run time.
Works OK as a flashing warning up to a short distance since it's only 60 lumens. But battery life is awful, so don't bother if you want to ride for more than an hour or so.
I don't use this light as a night visibility tool. I primarily use it to alert drivers on the other side of narrow roads in my neighborhood that I am out there. I use another light on my seat post to warn drivers behind me!
Love this little light.
I use it in the flash mode to be more visible to motorist, and have it mounted on my fork so I am visible when coming to and crossing an intersection.
I also use a taillight.
I also really like the convenience of the usb recharge.
The only thing I would like is that the onoff and selection function which is accessed by pushing on the lens was a little more sensitive. It does take a bit of pressure to make it work.
Used on front handle bars in strobe mode to alert oncoming traffic. It works well but the battery power only lasts for about 3.5 hours so if one is doing a long ride (35 or longer) it is out for the finishing distance.
Great headlight which is super bright and is excellent for letting others know that you are on the road. Not so sure of its use as a headlight to light up the road but as a blinky to let other know you are there is it a great light.
Neat design and worked well but only twice then it either wouldn't charge up or wouldn't switch on. I suspect the latter because I tried multiple cords and ports and it still didn't light up.
I always use a front flasher now. 4 or 5 bikes going down the road with flashers going get a motorist's attention, I hope. This one mounts easily and it switches onoffblink easily. I haven't done a calibrated trial, but it lasts at least 3 hours on blink. Might go 4.I haven't done any 4 hour rides this winter but one, I think it was still alive.I was too beat to check. It weighs next to nothing. I had been using a Knog. This is better.
