2GIG DW21R Recessed Door Sensor. Good?

I am upgrading (yes upgrading) my door sensors to the 2GIG DW21R recessed sensor. I almost used the DW20R, but it was difficult to open and you had to pull out the circuit board (PCB) to change the battey. That might result in damage to the unit. I left a link to a few installation videos, below. I just want to show how it works on my (soon to be extinct in my home), VIVINT control panel with old ADT sensors in it. Of course I won't install it. Just want to show that it works. It should also work for any (my opinion only) system that uses 345MHz sensors.
