    Rated 5 out of 5 by from Amazing Wipers Will only use Bosch wipers, everytime I buy a new car its the 1st thing I change as I like to see where I am going, yes there are cheaper alternatives but I find these last, and do the job I want them too,

    Rated 2 out of 5 by from Buy premium and get lkess than standard Every time I spray the windscreen the wipers end up spraying the water so it's never actually wiped clear. I like to pay for quality products so I know I'm getting the best so very disappointed I've not had such poor windscreen wipers since my little car 20 years ago. Don't buy

    Rated 5 out of 5 by from Great for curved windscreens Fitted to 2002 vw beetle old standard wipers were noisy possibly due to curved nature of windscreen. These wipers have a natural curve to them and so fit the screen more closely. I really like Bosch wipers, they work very well and last.

    Rated 1 out of 5 by from Do not buy These are overpriced, and for my car it involves throwing away the spoiler on the previous blade. I have kept that blade and simply replace the existing rubber on to that blade next time

Some of the parts we sell here at Halfords have been reconditioned. These will carry a Refundable Deposit or an extra surcharge amount. When you add one of these reconditioned items to your basket, we'll add this extra cost automatically.

Once you've sent us your old item we'll check it over, and then refund you the full surcharge as long as everything is ok.

Before you return your old unit please make sure it's in re-serviceable condition. So if you're returning caliper casings, you'll need to double check they aren't badly damaged or broken. If the part you've sent is found to be unserviceable, we reserve the right not to refund the surcharge.

Please note that if you're returning your old unit to our National Returns Centre then this will be at your own expense.
