I was so apprehensive before ordering this because I had no idea how effective this would be. But now since I’ve the product and I’ve used it, I can’t tell you how happy and thrilled I am. It stands by everything it says it does and is. Three levels of brightness which actually has three different levels and not just for the hell of it. Super easy to use and in works flawlessly in darkness. Blindly go for it. Only aspect I am yet to see is durability. Have to see whether it lasts. Will update the review after using it for a while.
