Very good quality materials - especially considering the purchase price. Good light and temperature grading (Kelvin) cold - medium - warm. Together with a small powerbank and a gorilla pod, it takes up minimal space in a bag, offering solutions for close-up photography and similar situations. If needed, with a suitable cable, it can also draw power from your mobile phone.

Very good brightness and light diffusion in the space. Wide range for dimming. 3 lighting options (cool, warm, intermediate)

It may be smaller than it looks, but it does an excellent job. Besides, if someone wants higher intensity and color range, they will have to go for something much more expensive. With just 6 euros that I bought it for, it really does what a 20 euro ring light does. Obviously, due to its size, it cannot go very far and it does not fit a mobile phone in between, but a c920 camera or a similar one fits perfectly. Personally, for video streaming and video creation with a webcam or a lens, this is what you are looking for.
