I have a few toy drones and a Phantom 3 Pro. When it comes to stability, distance, and video quality, you can't beat a DJI drone.
However for the money, this looks like a nice drone if it does what it says. Technically however you CANNOT fly with the goggles on unless you have a spotter right next to you since the rules say that the drone must always be in direct visual contact of the operator.
As to registering, YES you MUST register with the FAA if you are flying any drone above 0.55 pounds. The rule was suspended a while back but was re-instated last December. As long as you are flying recreationally (not commercially, making a profit) then you only need to register once and it covers all your drones. The cost is only $5 and it takes about 2 minutes. Very simple. Then you must display your FAA issued ID number on the drone itself.
Oh lastly, I don't like drones that depend on your phone for controlling the drone. A dedicated remote is the way to go. Too many issues with phones.
