First off, this bike light is BRIGHT. Like 'accidentally-blind-your-neighbor' bright. I took it out for a night ride on some unlit trails and it felt like I had car headlights strapped to my handlebars.

The waterproofing is legit - got caught in a downpour and this thing didn't even blink (but the lights kept working perfectly). No more worrying about sudden rain ruining my ride.

Love the multiple light modes. The daytime running light is genius - makes me visible even in bright sunlight. And the different flashing patterns for the taillight? Cars actually give me space now.

Mounting took some fiddling though. The clamp is sturdy (maybe too sturdy) - I ended up using just one mount point after struggling with alignment. Pro tip: keep an Allen key handy for adjustments.

Battery life is decent - lasts through my 2-hour commute with brightness to spare. USB charging means I can top it up at work or in the car.

Would I buy it again? Absolutely. It's transformed my night riding from sketchy to spectacular. Just maybe pack some pliers for the initial setup!
