The media could not be loaded.I regularly run between 4:30-5:30 in the morning, so my top priorities when buying a wearable light were that it made me visible to cars and didn’t rub or bounce around on my body. First let me speak on the light. It is quite bright and I am for sure visible to vehicles coming or going. The lamp can be angled down (like in my video) or straight ahead. After I recorded the video I played with the angles a little and actually decided I liked it straight out instead because it helped me see my surroundings a little better, but I couldn’t see the sidewalk in front of me quite as well. If you walk/run on uneven surfaces, straight down would probably be a better option.As for the comfort of the light, I barely notice it at all. It fits snugly around my chest and I don’t have any issues with the shoulders rubbing or sliding down. The lamp itself stays put on my chest, but because of the way my arms/shoulders move, the beam of light bounces around a lot and in the really dark parts of my route, it almost made me feel a little motion-sick. I grew accustomed to it after a few minutes though and it didn’t bother me after my first run. I think wearing the light in the straight out position did help. This is a non-issue if you’re walking.I’ve worn it 3 times now and my initial thoughts still hold up. So far it’s been on for a total of about 2 1/2 hours right out of the box and I haven’t needed a charge yet. Also, during one run, there was a light rain falling the whole time and it didn’t seem to affect the light at all.
