This flash light is good to have for emergencies. I got this so that we would have something if we have a blackout or if we have car issues at night. This illuminate bright enough at night to provide you with a lit area. This has a soft and comfortable wrist strap that hangs on the end. I like that it is waterproof. The strap is good to have so that you can have this right at your hand when you need it. One unique thing about it is that it has a hook clip on it so you can take it off if you don’t need it. There is also a button on it to adjust it to fit onto your wrist properly. You can get one here http://www.amazon.com/BlueFire-Tactical-Waterproof-Flashlight-Batteries/dp/B019DQ6XAC The power button to this is on the bottom end. It is large and easy to press. This does not come with the battery so make sure you have one or plan on buying one. The batteries are not your average AA ones, they are 18650 or CR123A; you can get them on amazon. This flashlight handle is about the size of the palm of my hand so you can get a good hold of it. Overall, this is a good flashlight. I received this product for free in exchange for my honest and unbiased review.
