Before getting this, I used clip-on lights that I'd often forget to turn on or would fall off during rough rides, leaving me less visible and more anxious, especially when biking with my kids in the evenings. Now, with this product, it just works automatically—no more fumbling or worries. It's made my commutes and fitness rides feel safer and more carefree, which is a huge relief. As it seemed to me, it's a practical upgrade that delivers on its promise without any frills, though it's not perfect for every scenario. I'd recommend it for its ease of use and reliability, but be aware of its limitations.
- Pros: The automatic activation when I start pedaling is incredibly convenient, as it eliminates the need to manually turn it on or off, which was a constant hassle with my old lights. The brightness is more than sufficient to make me visible in traffic, and the build feels durable enough to withstand daily use and minor impacts without issues. It's a simple yet effective addition that enhances safety without any effort on my part.
