Conclusion: The Notevision XR-1S from Sharp is a tiny projector that makes big, bright images. It has some limitations and relatively minor display-quality flaws, but it costs only a few hundred dollars more than similar projectors that weigh twice as much.
Pros: Extremely small. Bright image for a 3.2-pound projector. Good printed documentation.
Cons: Fairly noisy. Small remote with fewer buttons and tiny legends. Limited connectors.
