I teach virtual dance classes and decided to purchase this product in September to use during class. A few weeks were great. My classes are 45 minutes and for the past few weeks this ring light has only been on for about 30 minutes of classes. After that, the light goes out. The cable connected to the wall and the box overheated. I'm very frustrated considering I spent $45 on this and now I feel like I need to buy a more expensive ring light to last for a long time.
