Unfortunately, this arrived already broken, to have ever put even without them in a window. As I have tried (unsuccessfully) to repair the existing fracture between socket and cable, unfortunately I could not return the thing.
Ultimately, the cable was then unsuitable for my old windows because it is too thick, so I opted for an even thinner (though at the cost of poorer shielding).
Two stars for one - as I know from the past - really decent cable, deductions for bad final inspection / defect upon delivery and only limited usefulness in some windows.
