This is a small flashlight from Gentos. Model: NEX-971R It's bright despite its small size, as you'd expect from Gentos. I have confirmed that the brightness adjustment and flashing functions work. There are some minor scratches on the right side of the body (where the battery is replaced), but there are no scratches on the lens or around the lens. Charging is also not a problem, but please note that the instruction manual states to charge at 2.0A or less. Since this is a used item, the battery life is unknown. A charging cable is included, but an adapter is not. Please understand these points before bidding.
