- Reviewed in the United States on April 17, 2025Great product! I bought it to shine on rocks, it does just that. Has a bright light, good handle! Not a bad price and seems sturdy.
- Reviewed in the United States on February 27, 2025This works so well! The filter light works perfectly, it’s comfortable in the hand and it has a loop to put around your wrist. Which also comes in handy, so I can hang it on the door knob of the hall closet, that is where our newly adopted shelter kitties spray, right outside my bedroom door. I can see where the urine stains are and catch them in the right spot. Very easy to use, love the design and definitely worth the money! Thank you for offering it here on Amazon!

- Reviewed in the United States on April 18, 2025This light was great. Did not realize how much things you miss when you clean. Especially with pets. Wonderful product.
- Reviewed in the United States on March 20, 2025I have an 18 year old cat that has had an issue throwing up. I wanted the black light to see if the cleaning products I’ve been using were removing everything from the carpet.
This light worked amazing!! I used it first thing in the morning so it was nice and dark. The light had excellent brightness and showed stained areas very well.
A little too well. Yikes
- Reviewed in the United States on April 29, 2025This flashlight works well, but it arrived missing parts. It was missing a coil so I couldn't add the other battery. We had to fix it ourselves to make it work. Overall, the light IS bright enough to detect urine stains even when I had my regular lights on. I would recommend this product if you know how to fix missing coils from the battery.
- Reviewed in the United States on April 22, 2025This item performed exactly as described. At first I was unsure of what to look for since most items seemed to glow if they were white or a light color. Pet stains were visible under this light and gave me an accurate assessment of furniture and rugs. I am glad I purchased this light even if I only use it once or twice a year
