### ⭐⭐⭐⭐⭐ Review
*by J***M on 3 January 2026*

These UV flashlights work as expected. They are inexpensive, lightweight, and easy to carry in a pocket or small bag. Build quality is basic but acceptable for the price, and nothing arrived damaged or defective. The UV output is usable and does what I needed it to do. That said, the color frequency seems slightly off compared to higher quality UV lights I own. It still lights up materials and surfaces clearly, just not with the same intensity or color accuracy as more expensive options. For casual or occasional use, these are perfectly fine. I used them to illuminate a few different items and included photos showing the results. They are convenient to keep around and work well enough for quick checks without worrying about losing or damaging a more expensive light. Overall, they are a good value if you want a simple UV flashlight that gets the job done without spending much money.
