I first read about Quartz and their new book coming out from Hustle article, which I very much like and enjoy. Was very excited to order the product as a gift, but unfortunately did not receive the book on time (by any means this was not Quartz fault). When I inquired about the return policy, customer service was unable to provide an info on what the return policy was and was told to return the book through Amazon (I did not order via Amazon and so could not return). After few days customer support got back to me with a return shipping label (but not a prepaid one). Again, there was no mentioning of customer supplying their own return label in Quartz return policy. When I inquire about the matter with customer service, have never heard back. Overall, great product, unclear return policy, lack of info from customer service.
