I would recommend getting a similar one off of ebay there are more options. ### ⭐⭐ Didn't work very well for me *by T***W on Reviewed in the United States on January 12, 2020* I completely charged it, and several days later used it to power a 5-LED Sahara Sailor bicycle light. It worked well at first, but it didn't last even half a long as it should have. It was dead in about 45 minutes.I'm not a big fan of the Velcro straps. I attached it to the top tube, and it slides back and forth a lot. The rubber straps on the Stupidbright-style batteries are much better. ### ⭐ Completely Useless *by A***R on Reviewed in the United States on September 24, 2020* The light randomly shuts off. You might get 30 minutes of battery life. The changing of the light from green to red to indicate low battery is worthless.Do not dare to use this light on a bike. Especially in the woods. You will be stranded if you don't die from wrecking.
