Replace my Sonos Gen one ( pair) with a pair of Era 100. Really pleased with the new speakers. Worth the upgrade in my opinion. 

The setup was not straightforward. Initially used my phone to set up the first speaker only to have an error message ‘ another App using airplay’ Could not work that out so I used my iPad. All went OK.  There was an issue with Alexa in that I couldn’t get Alexa to work with the new speakers. Seems that was my fault for trying to add the new speakers with the same room name I used on the Sonos ones. Changed the room name and all was well.  

Overall I am impressed with the pair of Era 100. They sound terrific as a stereo pair.
