I have tried literally 4 other rings before. None of them are comparable. I honestly tried them once and never again because they didn't do what they were supposed to do. This does EXACTLY what I need. I totally see the difference when I'm on a Zoom call and have a Zoom call for work at least every other day. My colleagues even commented on how much brighter my surroundings look. I also like that it literally snaps into place and plugs straight into a USB port. Another good feature is that it is small and portable. I can take it anywhere without feeling like it's cluttering up my laptop or needing a stand. HIGHLY RECOMMENDED
