I’ve been struggling with them long enough that the temptation to just rip them out and go without any is very strong, but then I’d be worried about dirt and water ingress….but frankly, even if they were working perfectly I’m not sure how much difference they’ll make anyway since they don’t create a very good seal even when you have the cables exactly straight on either side.
And I think mine are a little twisted in the front frame such that they want to exit through the middle of the opening rather than straight through the sides. That’s not necessarily something I think I can reliably change even if I did my cable routing all over again. What the cables do that deep in the frame isn’t easily visualized or controllable, even with a magnetic routing kit.
