Hi there, thanks for leaving a review!
This does sound like they're not performing as intended- sorry to hear!
We'll need to check first on the installation of the product, as it's possible this was not installed correctly.
Good news is we do have a 12-month warranty on all our blades, this includes any performance issues. Not to worry, we will resolve this ASAP.
I've emailed you directly to offer further assistance, as well as express post replacements if needed.
Do get in touch with us!
Cheers,
Jean
Wipertech Team
