BESTSUN Diving Headlamp, 1800 High Lumen Diving Swimming Headlamp Light Waterproof Underwater Diving Head Flashlight Diver Submarine Head Torch Scuba

The BESTSUN Diving Headlamp is a versatile and waterproof head flashlight that can be used for diving, swimming, and other underwater activities. It is designed to be used with rechargeable lithium batteries for optimal performance. While the product claims to be waterproof up to 150 meters, some customers have found that it is only suitable for shallow depths such as 3-5 feet. One of the key features of this headlamp is its versatility, as it can also be used as a normal flashlight by removing the strap. The battery life is reported to be long-lasting due to the use of a high-capacity 18650 lithium battery. However, there have been several complaints about the functionality of the headlamp. Some customers have experienced issues with it not working even with new batteries, while others have encountered problems with the plastic caps stripping off when tightening, rendering the headlamp useless. It is worth noting that the product does not come with detailed instructions, but users have found that it is fairly easy to operate. The lever behind the lens cap turns the light on and adjusts the brightness, and the black ends of the light body can be unscrewed to load the battery from either side. The headlamp also includes the necessary strap. Overall, the BESTSUN Diving Headlamp has received mixed reviews from customers. While some have found it to be a reliable and functional product, others have been disappointed with its performance and build quality. It is important to note that the return options for this product may be inconvenient, making it more difficult to get a refund if needed.
