Finally got my pair of Fives and Stands. Absolutely fantastic. Whatever I throw at them, Rock, RnB, Pop, Jazz, Classical. Just brilliant. So much power yet so much subtlety.
I went for these stands at about half the price of Sanus etc and I am delighted with them. Premium look and feel (more so than my Sanus stands on my Ones). The bracket holds the Five securely. Impossible for it to fall off. No rattle whatsoever. All the screw holes etc really well machined. Look really nice too with a subtle metal ring detail at the top of the column. Highly recommend:

I'm finding the app pretty much fine these days too. Quick tip for anyone who hasn't found it yet... If the app isn't grouping when you try, open up the web app and group there. That always works for me. Then I go back to the Android app.
I have a shortcut to the web app on my phone, so it's a very quick process. If you use Google Chrome on Android, just make sure you are viewing the web app page as a Desktop Site (form the 3 dots overflow menu).
I also have an old Samsung tablet plugged into the mains in the living room and have that constantly on split screen. Web app on the left, Android app on the right. So everything's right there.
Hope others are having a good experience. Absolutely love my Sonos.
