Fantastic experience returning my Era 300. I followed Sonos directions for returning merchandise and the day they received my return they processed my refund.
Customer service was quick to respond to my questions and provided helpful information. On 2 seperate occasions I had issues with my orders, both were problems I created. Customer service was excellent in helping me and I have no worries should I need assistance in the future.
All in all, my experiences have been positive and their customer service is a model other companies should strive to emulate.
