Don't bother with S+S screen cover. They don't fit properly on a T6/6.1 If you look very closely at their photos on the website, you will see that the screen cover is shown fitted on a face-lifted T5 which still has the original mirrors. The mrirrors on a T6/6.1 are in a different place and the screen cover doesn't fit properly, or at least in my experience not properly enough to my satisfaction. We had one and sent it back within a couple of attempts to fit it.
Ended up buying one of these. If you're not bothered about insulated, fold down with comedy eyes, can't go wrong at £35
