Hi there, thanks for leaving a review and raising our attention to this!
It sounds like the blades are not performing as intended. Noise related issues are commonly caused by the wiper arm instead. So we'll need to check first on the installation of the product, as it's possible this was not installed correctly.
The good news is we do have a 12-month warranty on all our blades, this includes any performance issues.
I've emailed you directly to offer further assistance, as well as express post replacements if needed.
Hope to hear from you soon!
Cheers,
Jean
