Hi Andy, thanks for posting a review and letting us know about your concern here!
It sounds like you may have purchased wipers not specific to the build year of your car, as most manufacturers change the wiper style/length from time to time.
The good news is we do have a perfect fit guarantee along with our 12-month warranty. We will have this resolved asap.
We've emailed you directly to offer further assistance on the correct set you need via express post replacements.
Hope to hear from you soon!
Cheers,
Jean
Wipertech Team
