Taper Pro Polarised Wheel Nuts

As per the title has anybody replaced their standard wheel nuts with these?

I know it's been covered before on here, but my standard wheel nuts easily seem to get spots of ginger coloured corrosion on them if the car has been outside for a while. It's easy enough to clean up but annoying all the same.

One of the guys over on Detailing World has fitted them on his 172 (http://www.detailingworld.co.uk/forum/showthread.php?t=188046&page=5). I was wondering what peoples thoughts are switching from OEM to aftermarket wheel nuts.

They look the business so I'm seriously thinking of splashing the cash!
 
Not for me but if you like them no reason why not. As long as they're a reputable company using suitable materials when a wheel nut is a wheel nut
 
I don't want to look a chav!

I do prefer black bolts but it's so annoying that they corrode. The car is out of warranty now otherwise I'd go and complain to Renault about them.
