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

I've had three of these lights for night diving in South Florida. They are exceptionally bright and the magnetic switch is easy to operate even when wearing gloves. The battery life is long enough with high power for the entire dive. The only problem is after 20-30 dives 2 out of 3 headlights are flooded. The seller was quick to respond to this issue and sent me two new lights prior to this weekend's dive which worked fine. During the first morning dive one light started to fail and eventually went out (later on the surface I saw the light flooding), later the next day on a deeper dive my second light went out (same problem. Flooding) . At the same time, the original flashlight that I bought a long time ago survived almost 75 dives without a single problem. Maybe a bad batch, hope the leak problem is fixed, otherwise good product.
