OK, it's come and looks pretty OK too - there are choice of colours too though I figured any kind of painted finish will attract scratches (and that's what I'm trying to avoid) so went for plain black. The cost, delivered was £54.08.
Packed simply with both printed instructions and a clear diagram along with a 3M wipe to remove any traces of silicone polish from the bumper surface - a couple of pictures prior to fitting:
The instructions were usefully sensible, suggesting that the two short pieces of protective tape at either end were removed and the item offered up, whilst removing the 1st 300mm or so of the protective tape on the long (rearmost), leaving the tape hanging down and only completely removing it once the reference points for correct alignment being where the curved edges of the strip meet the light aperture in the rear bumper.
I think it looks like it's meant to be there and has clearly been made to do the job. I've been ultra careful and even have the reversible boot mat with protective bumper cover which you can see tucked under the luggage net in the images below and the top of the bumper surface still has marks on it. I like the way the protector goes right over the edge of the bumper, neat but probably not to everyone's taste.
