When it works it's convenient. However now getting stuck on a really weird bug that shouldn't exist. To add a speaker, app is asking me to update the app with link to Google play. In Google play there is no update available. There doesn't seem to be a very reasonable excuse for why you would need the app updated anyway just to add the speakers already. Additionally the Android app does not support calibration (even with external microphone) for rooms unlike the IOS app.
