This light is rock solid - as most Lezyne products are. I've been using it for a couple of months now on my daily commute as well as longer road rides. It mounts very secure and is easy to take off and put back on again - I recharge it once a week but feel like it would last much longer. Have yet to run the battery out. USB charging is a big plus. Very sturdy and definitely waterproof since I've been riding in pouring rain over the last months.
The only light ive found that is truly waterproof riding in the pouring rain.
But the strap is weak, literally and figuratively. It doesn't connect securely and breaks after a couple months use. I've lost all my lights because they fell off. ??
Love the choices of light blinks etc. the light lasts on bright blinking for 8-10 hours before needing charging.
Easy to take on and off bike seat post. I have an aero seat post design and the light stays facing back.
Light is small, easy to attach, bright, long lasting and easy to charge. I have a radar/light combination but riding at night or in the rain I wanted more visibility. No room for a seatpost light especially with my seat bag so wanted a small seatstay light. This worked perfectly.
This was a little hard to mount only because my seat post was flat on one side, but that wasn't the lights fault.
The light works good. Nice and bright with many mode options.
