Unboxing and First Impressions
The Planet Bike Rojo 100 arrived in Planet Bike's signature eco-friendly packaging – cardboard, no plastic in sight. The packaging is thoughtfully designed, showcasing the taillight prominently and allowing for easy access to the contents.

The included accessories and mounting hardware were well-organized and easy to locate. This attention to detail is a positive first impression. The instructions were clear and concise, aiding the setup process greatly.

Features and Specifications
Boasting 100 lumens, the Rojo 100 packs a powerful punch for both daytime and nighttime visibility. It offers standard modes like super flash and courtesy, catering to various riding conditions. A key advantage is the inclusion of multiple mounting options directly in the box.

Unlike many competitors that require additional purchases, Planet Bike provides everything you need for rack, seat stay, or seat post mounting. The built-in 650mAh lithium polymer battery with USB-C charging is a modern and convenient feature.

Mounting and Accessories
The package includes a seat post mount with a rubber strap and sliding locking mechanism. Additional hardware for rack mounting is also provided. The rack mount cleverly incorporates a body clip for alternative attachment points like backpacks or saddlebags.

The included seat stay mount allows for lower-profile mounting, providing flexibility in placement. The multiple mounting options truly set this taillight apart from the competition. The versatility offered is exceptional.

Design and Build Quality
The Rojo 100 features a compact, two-LED design with a prominent upper LED and a honeycomb textured lens for diffused light. The lower LED, while smaller, also contributes to visibility.

Excellent side visibility is achieved thanks to the transparent lens body and reflective design. The power button, however, is small and may prove difficult to use with gloves. Overall, the build quality is solid and durable.

Comparison with Other Taillights
Compared to Planet Bike's Superflash, the Rojo 100 offers a more modern design and higher lumen output. The Topeak Redlite Mega, while powerful, lacks the compactness of the Rojo 100.

The Phoenix BC OV 1R, another USB-C taillight, falls short in terms of brightness and side visibility. The Rojo 100 offers better value and performance at a lower price point. Other lights have various strengths but may lack the versatility of the Rojo 100's mounting system.

Real-World Performance and Conclusion
The Rojo 100 provides excellent daytime and nighttime visibility thanks to its 100-lumen output. The multiple mounting options allow for adaptability to different bike setups and preferences. The four light modes provide flexibility.

However, the small power button and bulky mount are drawbacks. The lack of a precise battery indicator is also a minor inconvenience. Overall, the Planet Bike Rojo 100 is a fantastic taillight, especially considering its price and features; a solid 9/10.
