Review on Genwiss Dive Light - Underwater Flashlight for Scuba Diving Activities | 1000 Lumens, 80M Depth | Rechargeable Battery & USB Charging by Nguyen Taylor

Bought two of these. I love the ease of use and the build quality. But both lights leaked and were damaged on the first dive. The depth was only 30 feet. Of course, I didn't tighten them as tightly as I could, but I did tighten them as much as seemed reasonable. The two O-rings seemed to provide a good seal, but not good enough in my opinion. Edit: I was contacted by a seller who offered to refund my money if I edit or delete this review. I declined because I think people should know the product. So the seller refunded my money anyway and I added a star for good customer service.
