The Serfas Thunderbolt USB Headlight is a compact and bright front light for bicycles. It throws a bright glow in a 120 degree arc and is highly visible to prevent accidents. However, some users have reported durability issues with the power button and battery life. Additionally, the older mini USB design and difficulty in charging the light have been mentioned as drawbacks. Overall, it is a solid light for being seen, but improvements could be made in terms of durability and charging convenience.
