Review: Great value and easy to use - TLDR: I'm very happy with it. I like the Garmin mount. And it's easy to use. I've purchased a number of inexpensive bike lights over for years. I'd find an inexpensive one and over the next year it would eventually die. The battery would go bad or something in the mount system would break. I'd find another one and wash/rinse/repeat. I commute by bike to work most weeks of the year in the midwest and we get some cold weather and can hit some extremes in both directions. OK. Fine. I was buying cheap, crappy lights because I didn't want to spend the $$. And yet I paid more over the years because I was a tight*** fool. This light is solid and the button is easy to use even with gloves on. I like the Garmin mount. I do wish I could adjust the light position left-right insead of up/down but that's a minor issue. I tried a number of different USB-C cables (A-C and C-C) and they all charged the light. I haven't been able to really test the length of charge since my rides to work are less than 2 hrs each way. The rubber cover for the charging port covers it very well and seems sturdy. It's bright enough for me since I ride on paved trails and roads. If you you aren't sure if this will be bright enough then you probably want to get the next level up. I'm happy I decided to spend a little more $$ and get a better light. I think this one is worth it and the light and mount system build feel sturdy enough to last much longer than my previous lights.
Review: Great quality - Work amazing, I’ve had them on bright for 2-3 hours before they die. Ended up with 5, work on Honda 50s also for night rides. Super bright
