It's sufficient
I’ve included two photos. One without the light on and one with the light on. It either clips onto your monitor or you can use the included tripod stand. My webcam fits nicely in the ring.It’s relatively intuitive use. I like that it plugs into the computer USB so I don’t have to worry about batteries or finding an outlet.It’s sufficient for my purposes. Wish it was a touch brighter so I could sit further back but it’ll do the trick.
