I've just fitted these to my 156 and thought I'd pass on my findings...

Pros
- Visual impact of parked wipers is much reduced
- Very easy to fit
- Wipe beautifully - smooth, silent action

Cons
- Passenger side wiper is shorter than original curved wiper - reduced screen coverage
- Passenger side wiper can't cope with the curvature of the screen - tried bending it a bit more, now it lifts off in the middle of the wiper
- 156 owners will know that the screen washers are crap because the jets hit the wiper before the screen; I thought the low profile blade would help but, no, the jets hit the 'integrated spoiler' and it's worse than ever
Verdict - stick with conventional wiper blades on the 156.
On the plus side:
- Service from www.wiperblades.co.uk was excellent
- They stock replacement rubbers for the rear wiper of 147s and 156SWs, I didn't know these were available, only £3.25 too
- A tank of Shell V-Power Diesel and a long, fast journey has got my JTD running nicely and reduced its smoking habit
Hope this proves useful, cheers,
