Acceptable quality. Plastic, but it doesn't feel that bad. The included USB cable works surprisingly well as a charging cable. Bring two adapters to try and adjust the width of your monitor. However, if your monitor's frame is thin, the lamp base may interfere a little. I had to put on a sock of about 4mm to raise the lamp so the base didn't make my monitor look like that of a Macbook Pro M1 Max with the "notch" in the middle. If your monitor has an integrated camera, you'll need a sock of around 12mm so it doesn't get in your way. It seems to me that the LEDs and the diffuser need the most improvement. The light is still very harsh and this affects the reflections on the screen. The shape of the lamp allows the light to hit you slightly from the front if you don't adjust it to point practically straight at the desk and can create more reflections on the monitor not from the objects on the desk but from the material of your screen itself. This angle looks good in the first two photos. You should not be able to see the light source from your working position. In the second photo you can see that it shines slightly from the phone camera as the intensity of the light your face receives can be important (and uncomfortable). It's worth noting that my monitor has a textured/matte screen that minimizes reflections. Even if you have bright things in front of you, they can be reflected. I'm not sure if other options available here solve this problem well, but this option can be tricky to change if you're interested in having a clear view of what's in front of you while keeping your eyes out of conventional ones protect lighting. The light sensor seems to me to work exactly the opposite way I'd like it to, although that's just my own preference. It works the same as the opposite of your phone screen. The more light there is in the room, the lower the brightness of the lamp. When the lighting is low, the lamp is adjusted to a higher power. For me it should be the other way around but I insist it's just my preference. I hope it helps you...
