## Customer Reviews

### ⭐⭐⭐⭐⭐ Worked as expected
*by G***. on April 25, 2024*

Fast delivery. Worked as expected.

### ⭐⭐⭐ It works well
*by S***L on October 24, 2025*

The only reason I gave it 3 stars is because when I gave it to my dad he finally said he was going blind. Make sure you can read the window

### ⭐⭐⭐⭐⭐ Used for a science fair project
*by L***N on January 25, 2020*

I used this with a student's science fair project-- the UV detector picked up the highest UV rating with a blacklight bulb. The student measured UV on the other side of a pane of glass with different sunscreens on the glass. Great product! Simplifies UV measurement quite a bit.
