Anyone here use Google Allo?

Google Allo is massaging app similar to iMessage. It connects to your phone number and it has many features like a great material design, the Google assistant, and special emojis and other things that I can'tthink of

From my experience it creates a completely different phone number when trying to SMS someone. And it says "sent by Allo". I'm just not sure if it's any useful other than SMS Though.
