30% is not no margin. People always claim this. It may have less margin then some other products, but you can still make money. Sell Connects and you still can get an amp and speakers sale, plus labor. Sell an Amp and still get speakers sale and labor. Sell the play line and and get in and out in less time then it takes to gas up the van, plus labor. At the end of the day, year, decade, you will have zero Sonos related service calls. You'll likely get called to add more and be referred to others. I haven't found a single product that offers the benefits of Sonos.The downside is Sonos the company. They will try to sell your client. Have a so-so client and they will circumnavigate you. Have great clients and they will still come to you. Integration. It's better then it was in terms of reliability, but not great. It is limited in functionality. I only use it integrated in one of two.scenarios. They already have Sonos and want to continue to use it with a new system. 2, the streaming source is available only on Sonos.Lastly, I have never, not once, had a customer complain about sound quality via Sonos. In fact, quite the opposite. They've all LOVED it, whether it be a connect streaming to an amp, a connect:amp, or a play series speaker. I've never NOT had people amazaed at the quality and overall package. Just my experience with my clients.
