This is by far the coolest selfie light I have ever seen! I was shocked that it came with 9 levels of brightness. Another cool thing about this selfie light is that it also has a mirror on the back were you can fix your makeup or anything you'd like. The mirror also comes with lights and these have 3 different brightness settings. Battery life does last quite some time and this is rechargeable. I have an LG v20 with quite a thick case on and the clip opens up enough to fit my phone.
