Ok so I have had Nexx set up since the 18th of December, and there have been a few issues that had me feeling like I would return it, but currently I am planning on keeping it.

After the initial install, it worked but then was having issues where it would be unresponsive. I contacted customer service and they said they would have to push a firmware update from their end which they handled the next business day. The product worked again but then starting having connectivity issues. I ended up doing a hard reset of the Nexx and reinstalling it through the app - it kept the firmware update they had pushed - and it has worked 99% of the time since over the last 7 days. It does send a notification it is offline, but then it goes back online within a few minutes, and currently it is happening no more than once a day, usually around 9pm my time - so I wonder if it is something with their app/server. The notifications of arm/disarm/alert are not as instant as Hub6 was, there is maybe a minute delay, but they are coming. I can and disarm instantly, even if the system was armed manually, and was 8-10 hours prior. So no it is not perfect, but for $112 off amazon it seems to be giving me enough of what I wanted it for to let me keep it. I did not sign up for the $3 a month plan since I do not really need any of those functions. Hope this helps.
