Mine have been operating reliably. Once I managed to get the hub to actually discover them. Their pairing process has been very unreliable or perhaps just inconsistent. But once paired they've stayed working, doing their scheduled moves. Their app is definitely 'less than ideal' but it does work for making small changes to shade positions in order to match up their positions (when you have multiples in the room and want their appears to look even). But once I set up the scenes I have not gone back to the app. Sort of like Lutron's app in that regard.
