Review on Convenient USB Volume Control: DROK PC Speaker Audio Remote Knob with Mute Function - Compatible with Win7, 8, 10, XP, Mac, Vista, Android by Ricardo Fast

This volume control worked right away as soon as I connected it to my Win 10 computer. It even works through 3rd party KVM switch to control 3 computers. Does everything that is in the description. The light can be turned on and off, the volume changes gradually or rapidly if you press down while rotating, and the mute is instantaneous and positive. With a weighted metal base and non-slip feet, it stays in place when you twist it and spins very easily. It comes with a very nice fabric covered USB cable that looks smart. So why only 4 stars? The rotary switch shaft wobbles a little in the hole and wobbles back and forth with slight lateral pressure. So if the slight movement at the edge of the beautiful 40mm wide aluminum handle is overdone, it wobbles almost 1mm when you use it. This makes this otherwise perfect little accessory feel cheap, as opposed to the silky feel of a typical Alpine volume pot, and detracts from the overall quality of its solid metal construction.
