I have been a huge fan of Sonos for many years but just had one is probably the worst customer service experience with any company that I can recall. 

I purchased a Sonos Roam with the idea that I could use it in a small room in the house on Wi-Fi and bring it to the office to use on Bluetooth. Unfortunately, there is a problem with the speaker where it powers off on its own randomly anywhere between 10 minutes to an hour. I reset it to factory settings, without resolution. After 90 min (mostly holding) w tech support, they could not figure it out and wanted me to video the speaker to capture the random moment it powers off. I explained that I do not have time to waste doing that (could be 45 minutes or so of recording). They then told me to call sales for an exchange.  After another 30 min w sales, I was told it would be escalated and I would get a return call.  2 days later I still did not hear back, and called again.  After another 30 minutes, I was told its 10 days past the 45 d return window so they cant now exchange or refund. 

Anyway, they have lost a loyal customer and I would advise everyone to certainly avoid the Roam. The other products are great as long as you never need customer support; personally I am done with them completely.  I predict bad things ahead for this company.
