Hi there. It is not required to register your products, although it is advised. We are working to improve the online registering experience with our website. In the interim, I suggest you fill out the card the products came with and mail to our office at the following address. Please keep in mind it is best to save your receipts for proof of purchase. This is most important if you ever have a warranty issue.
