CGM alarms and partners - what's your experience?

I have one of these for my phone and the associated bedshaker. I assume when I get a G6 it will work with this as understand the G6 has vibration alerts. Since my has pump never connected to my phone, the dog has been trained for years to alert to the pump alarms.
