Google Wifi

I'm currently considering the best ways to make my at-home network as fast and secure as humanly possible. 

I have a standard modem with an Almond smart router (which I love), but I'd like to find out if there are more superior options for my area. 

If anyone has used Google Wifi (their mesh network connection), I'd love to gather your feedback on them.

I would need 3 of them to cover my home so I am wondering if they will be worth the investment. 

Your honest feedback is appreciated.
