Extremely simple to set up and appears to "just work". Hopefully Apple won't break it with changes to the AirPlay protocol down the road!
While I bought the product immediately, it is more to support the author to improve the product. I listen to my Sonos a lot but I don't necessarily keep my MacBook Pro on all the time. That dependency needs to go. I do hope this continues to work. Apple is quick to change protocols and kill interesting products like this.
