For anyone who is interested, I ordered a pair from 'eurasia_seller' on eBay UK. They arrived the next working day by 1st class post. £6.29 delivered.
Supplied in plain white box with no fitting instructions. Inside was the wiper blade contained in an opened ended folded cardboard tube/envelope.
wiperblades.co.uk website mentions 'WB5' in their fitting instructions.
As far as I can tell, these look similar if not identical to the ones sold by wiperblades.co.uk.
No problems fitting them. But make sure the wiper blades are properly engaged in the wiper arm's C shaped hook. The flip down cover shown in the pics is purely cosmetic. It doesn't even touch the C hook when closed.
Update July 2012
I should emphasize I don't use my car much. ie. I am a low mileage driver. Anyway, 6 months on and the wiper blades still performing OK when it is raining.
Lately, I have though noticed with the longer 20" driver side wiper blade. The lower half of this blade appears to visibly judder as it moves across the windscreen. When it is raining, it doesn't create any extra noise though and it continues to clear the windscreen perfectly well at normal wipe speeds (I've not tried the turbo wipe speed mode). Only when the windscreen has dried up and I continue to keep the wiper blades on, then some noise starts to appear.
The upper half of the same blade, and the shorter passenger side wiper blades don't exhibit any visible juddering issues.
On a similar note, I had to replace the flat blades on a relative's VW and I noticed the OEM blades appear to be very 'stiff' in construction in an arched shape to try and maintain maximum contact pressure at the tips of the wiper blade. I think they were 28" length. (The factory fitted flat blades lasted as astonishing 8 years and 45k miles. The wiper blades when parked are hidden below the bonnet which may be a reason for their long life perhaps)
