Not bad for the price I paid. I find the colour modes useless and just a gimmick, especially the rainbow mode. Light can get very bright with three different tones of white (6500K, 4000K maybe 5000K, and 3000K). Runs off USB. I have it connected to a laptop with no issues. Just two "could be better" items for me. 1) The controls is attached to the USB cable and is too close to the light. This means if you clamp this to your monitor, chances are, you'll have to reach behind your monitor to turn control it. 2) The clamp has a foam padding for protection, but it's huge compared to monitor bezels these days. If you fully clamp it, the clamp ends up clamping part of your actual screen so it blocks the view. On a laptop, it's scary because of how thin the screens on. I ended up using the clamp as a stand and placed it on my table instead of clamping it to anything. Would be nice if it was one of those adjustable arms that you find on most of the Logitech webcams.

Good lighting

I KNOW YOU SAY THAT THERE ARE 10 BRITHTNESSES AND 3 COLOR MODES BUT WASNT EXPECTING THIS!

Good. Strong clamp. Nice light options.
