Anybody had any experience of these low profile blades?

Aerotwins are very good, I've added them to my last 2-3 cars that had standard wipers and noticed a smoother sweep and less lift and drag at high speeds. However I would recommend going for a bosch ones as the 'unbranded' ones I tried tended to perish quite fast, where as the Bosches lasted a couple of years before showing signs of needing replacing.
