The media could not be loaded.
Now, most of the modes are useless, in my opinion, as I can't imagine why anyone would want jarring, flashing lights behind their monitor, but I ended up using the mode that slowly and gently shifts through the colors. You can also set the speed of the modes, and I went with the slowest.
My only real complaint, which is very minor, is that there is no documentation anywhere that I could find. They are simple enough to operate, but I would have liked to see a list of the modes rather and clicking through them all one by one trying to figure out what each one was.
Instead of plugging into the USB port on my monitor, I plugged into a USB adapter a couple of feet away so that I could turn them on or off using Alexa and a smart plug. There's not a lot of length to reach an outlet though so be prepared to either have an outlet within a couple of feet or have an extension cable of some kind (either electrical or a USB extension).
Overall, I'm totally happy with them!
