- Brightness Variation: While some reviews rate the UV light as sufficiently bright, others describe it as more of a colored light rather than a strong blacklight, suggesting limited intensity compared to higher-end models.
- False Expectations: A few users expecting professional-grade blacklight intensity or broad-spectrum UV functionality find the light somewhat lacking, emphasizing that the flashlight is best suited for casual household use rather than scientific or industrial applications.
Who Is It For?

Its compact design, affordability, and multipurpose capabilities appeal to a broad spectrum of users.
