Going on two years I've not minded the loudness. It runs next to my TV and the Sonos gets over its noise well-enough. 
It's a bear to clean though - rather to put back together after disablement to clean. It also doesn't tilt up very high (ok with me as I have it up on a bookshelf). 
After the two years it did stop oscillating but it's still under it's excellent 5 year warranty. 

In the end, my goal was to have something for occasional use that looks nice in the living room. I got just that.
