Good buy
Good price for these. The folks at Comcast wanted twice the money for the same thing. Adding them to my Xfinity system was a little bit of work (their software to add components isn't very user friendly). They work fine once installed.

Awesome price and worked with my Xfinity Home system. I got it set up in about 5 minutes. Just watch youtube for ways to pair devices with your Xfinity.

Compatible with the XFINITY system. Easy to install yourself. Cheaper than buying from Xfinity.

It works! Not difficult to install yourself.
I had no problem with installation myself. You do need to know the maintenance pass code, 4321, and to type in any letter for the name of the installer (it apparently doesn't care if "d" is the name of the installer.) I got this information from an open utube video after a simple search for Comcast security system installation. (Using your personal pass code doesn't show the installation options needed.) You get the panel into pairing mode (I think the panel describes it as sensor discovery or some such phrase.) Then press "next" and it finds the new sensor, lickity split. Then you can move the magnet away, hear the system acknowledge it with a chime, then put it close again, hear the system chime again... Now you apply the double-sided tape, stick it on your door (or window), stick the other part to the door frame, you get the idea. The included paper instructions show how to orient the sensor and magnet. Pretty easy.
