I've got one of these hooked up to a USB port on my monitor at work. I keep it a safe distance from my computer, as I've seen it cause problems with laptops before. It's not as visible as it appears in the pictures, probably why they have it in a dark environment. And it produces a constant high-pitch sound all the time, but I've gotten used to it and can block it out- it's not very loud.
