This little volume knob is exactly what I needed! I've used it on Windows and Mac computers, and it works just as described. Thanks to its tiny size, it's perfect for integrating into other audio projects. I'm planning to add it into the enclosure of a subwoofer volume control knob I already have so I'll be able to control my main speakers and subwoofer with just a single device on my desk. Plus, unlike many other volume controllers, this knob is all digital, so there's no concern about it affecting the audio quality. If you've ever been annoyed by a "scratchy" volume knob on your computer speakers, this item can easily solve that issue. Plus, the seller has been absolutely fantastic to work with. He went above and beyond to help me after an issue with shipping (not his fault at all!), and he's super responsive to my questions and messages. I 100% recommend this item and seller!
Small, unobtrusive volume control with smooth ramping and the ability to mute/unmute by pressing the knob down. There is a dim orange led in the translucent body which confirms clicks and volume ramping, which is a nice touch. Very convenient. Worked out of the box on Windows. Nothing negative I can think of. Quick delivery too!
