## Customer Reviews

### ⭐⭐⭐⭐⭐ Great price, fast shipping and one of the best flashlights that I’ve purchased.
*by D***  on March 5, 2025*

Incredible valued project.

### ⭐⭐⭐⭐⭐ AMAZING diving light! Absolutely love it.
*by T***E on August 4, 2023*

The media could not be loaded. Sofirn makes the best diving flashlights! Extremely bright, completely waterproof and never leaks. I recently purchased and used the Sofirn SD09L for lobster mini season here in the Florida Keys. This flashlight was in and out of the water and lasted all night without ever fading or loss of brightness. It is much lighter than other diving flashlights I’ve used in the past and lasts twice as long. Highly recommend!

### ⭐ One year later is not working !
*by T***L on December 20, 2024*

The flashlight it doesn’t fully turn on it doesn’t stay on and this light it was storage on a box I used probably 6 times and now is just trash
