What do customers say? How are the reviews?
On Amazon, as checked November 4, 2026: the 1st Edition averages 4.5 out of 5 stars from 732 ratings, the 2nd Edition 4.5 stars from 561 ratings, and the 3rd Edition 6-in-1 4.4 stars from 307 ratings. Common themes are that it's easy and fast to use, and that it catches fake UVC sanitizers. One reviewer wrote, "I had 3 different UVC lights for sanitizing and only 1 is worth the money." People also use it to check sunglasses, car windows and reptile lamps. Some reviewers say sunlight or UVA/UVB readings can be hard to judge; the card is mainly designed for testing UV light sources.

Do the cards expire? What is the shelf life?
We recommend replacing your card about once a year. That said, Quanta X Technology has tested properly sealed, unused cards over three years old and they still work like new. Store cards sealed, away from light and moisture.

Safety first

When designing a Far-UVC lighting system, current government, state or local exposure guidelines for UVC must always be followed.
