With its advantages, such as a clear image even when viewed from a distance and maybe a favorable cost-to-benefit ratio Some drawbacks include the fact that it can only be used in a standing posture, that it doesn't have a focusing mechanism, and that it can't be attached to anything. However, I'm not sure whether this is the typical for such cameras because I've never used one before.
