Ms K, Thanks for the email. Sorry to hear that your wiper blade did not have the adapters needed. Please call us at (800) 477-5847 to provide details on this issue so we can get it corrected. Thanks, PEAK Technical Product Support Department

Hi Kay, I agree the number of adapters needed to have a single blade fit 8-10 different arm types is complicated. Hopefully the videos are helpful in the installation process. A reminder, Sam's Club can install these for you. Sincerely, PEAK Technical Product Support

Hi Kay, Sorry to hear about your experience with streaking wiper blades. There are several reasons that this could occur: <br /><br />• Clean a dirty windshield <br />• Allow the coating on the blade a chance to wear off <br />• Remove the plastic protective strip that&#39;s on the wiper element <br /><br />Please consider the possible reasons and if none of these work please give us a call at (800) 477-5847.
