Hi Jessica, thanks for the review and we're sorry to hear that neither notch works with your Maui Jims or Blenders. While it's rare, we do have this happen on occasion. We have two possible solutions for you: 1. We have Notch-less inventory of that style still available. If you email us a few side pictures of you wearing your hat & glasses, we can custom-place notches on a new hat to make sure you have an optimal fit. We don't charge any extra for this service. You would simply need to initiate an exchange and select 'Notch-less' for the new product. As long as your hats are in new, unworn condition, we offer free exchanges. 2. If you'd rather just return the hats for a refund, you can do that as well. We appreciate you giving us a chance and for offering your feedback.
