Swissonic M-Control +

Works fine for one year, then the volume knob starts making noise when used (nothing critical). But after two years, the buttons become overly sensitive (probably due to a bad internal connection), to the point where the left or right audio signal randomly cuts out while listening. You have to gently tap the buttons to restore a proper connection.
I had exactly the same item two years ago with the same issues.
I definitely will not buy it for the third time. 😆

First the volume knob became scratchy and I have to move it around a bit or a channel drops out. Then the Mono button became unreliable and finally stopped working. After that the Mute button had the same fate. Now the input switching button is starting to fail. The unit was treated carefully and never even moved. I can't believe how atrocious the build quality is and how every single button and knob on this thing is either broken or nearly broken.

it’s a passive controller, but it makes noises
