I've heard bad things about retro fit flat bl;ades on cars that had "normal" wipers fitted before. I've always stuck with the Bosch replacements on all my previous cars and have had no issues with them
Quite agree Bob
But the Scenic IIs can come in at £50 a pair
so you can see how folk try other makes/brands etc.
I stick with the Renault ones I get very good milleage from them and they do clear the screen well and are quite in operation if maintained, Usually change my wipers annually tho
