I have spent over $1500 for my Sonos system which is less than 3 years old and now I’m told that my Sonos Bridge and Play: 5 speaker needs to be replaced before May or they will lose their functionality. All that Sonos is offering is a 30% discount on a new speaker, but I paid over $600 for these two products. I think this is poor marketing and strategic planning on Sonos part. If I had known your products functionality would cease after 3 years, I would never have purchased your product. Am I expected to upgrade various products of my system every 3 years? Your products are not inexpensive, so the average user must save in order to purchase your product. You are about to lose a valuable customer.
