Review on Sokani Selfie Ring Light with Cell Phone Holder and Stand Bracket - Perfect for YouTube, TIK Tok, Tiktok, Zoom, Video Conferences, Live Streams, Makeup - Dimmable LED Circle RingLight for iPhone and Android Mobile Smartphones by Brandon Mercado

I used this for Zoom meetings to provide extra lighting. I have an iMac and found that the ring lit arm is too small when pressed against the table. It's too heavy to attach to the top of a computer screen. I had to attach it to a shelf above my desk. However, this is a disadvantage as USB barely reaches the power source. However, it is positive that the ring light has many levels and you can adjust how much light you need or how much light is already in the room depending on the time of day.
