Great quality and perfect fit
Very good quality wipers which fitted perfectly. I went to Halfords and they said my car, a newish Mazda 6, would only take Mazda wipers and they didn't come in the Bosch series. Apparently I would have to go to a Mazda dealership. How wrong can you be? In translation it just meant they hadn't got them or were just very confidently wrong (a common fault I find). These fit perfectly having gone on the Bosch website and checked for my model car before ordering. Incredibly simple to click out the old ones and click in the new. It honestly took two seonds one each one. Halfords wanted £8 for the four second fitting.

Easy fit, doubt over whether it was the right fit, price variable
Easy 10-second fit to my Mazda 6, but it was hard work trying to work out whether they'd fit my car. This page not good enough to tell, but cross-referenced on Bosch's own website. Even then I didn't know if there was a difference between right and left hand drive. Price has been up and down, but basically I think I was over-charged by about £2

Good value product
Fitted in under a minute Halfords wanted to change an extortionate amount money now wipers are silent again with no streaks left behind great value compared to other places

A great wiper blade
Despite being told I had to buy wipers from Mazda UK suit my 2020 Mazda6 at 3x this price, these Bosch Aerotwin wipers fitted a treat 👍👍 Fitted in seconds.

Not a perfect fit
Despite Amazon telling me otherwise, the longer of the front wipers didn't for purposely on my mazda cx-5 2.0, I suspect because it wasn't specific enough, ie 2022 sport model. It slightly over reaches on the passenger side meaning the outer area of the 'swipe' doesn't clear properly. However, what contract it does have is very good. Having used it now I doubt I can get it replaced (plus I've already thrown out the old ones...lesson learned)

Mazda wanted $120+ to replace wipers. These are better than OEM and great value. Fitting take seconds

I purchase these for my 2022 Mazda 6 Wagon and it's a direct replacement, with no issues at all, 10-second install, unclip old one, and then clip in the new one. So far they have performed well.
