UPDATE: Now that I have had some time to use this thing a bit more, I have come to be very dependent on it and I am upgrading my review to five stars. The most important thing I have noticed is the amazing battery life. I recently did a century ride that took 11 hours. I was using my phone screen for navigation the whole way, and this thing was a life-saver as a power bank. I plugged it in to my phone when it got below 50%, and still arrived home with 25% of my phone battery remaining. Absolute lifesaver! I have also found that the mount has become more stable with time so I rarely have to re-position it. I also figured out that you can get good peripheral lighting from the reflector by pointing the light further up than I was originally doing. This means that most of my original concerns no longer exist and I am upgrading this review to five stars. Highly recommended! Side note: for those who still have concerns about the mount, I figured out that this is just a standard tripod mount and there are lots of handlebar tripod mounts out there if you want to upgrade. ORIGINAL REVIEW: This item does a lot of things for one unit, and as with other things that try to perform several functions, it doesn't excel at any of them. But I can say that it does work decently as both a headlight and a speaker for a bicycle. The speaker is not as loud as I would like, but it is louder and has more bass than my phone so that is an improvement. The light is bright enough to ride streets in the dark, but it is a narrow spot that it illuminates only right in front of the light, so you have to be very careful about what you are not seeing on the peripherals. I tried it on a night ride on a trail around a lake, and I had to go much slower than I would have liked because of the lack of width in the beam. The one thing that really falls terribly short of expectations is the mounting system. I got the swivel lock as tight as I could get it, but the light still tilts down forward as I am riding. I have been able to correct that by tilting the whole mount back on the handlebars so that the light is tilted as far forward as it will go when it is straight, but then I lose adjustability. Overall, I would recommend this if you want it for the speaker and just need a headlight to be legal or to make yourself more visible to cars on streets. If you are riding in a very dark area, you may need something with a wider beam area. I haven't tried it as a powerbank, so I won't comment on that function.
