Windscreen sun shade

[DrElectron]

Has anyone bought a sunshade for their windscreen?
Some companies offer properly fitted ones for about £100 which seems a lot for a bit of foil.
Some on Amazon for about £30 but seems to be generic so doubt they will fit nicely.

I'd be grateful for any recommendations

I have a 'Great Barrier' shield which I got from Amazon for about £15. Nothing special and takes a bit of working out how to fold it up but for me it works a treat and was cheap. It fits perfectly ok.
