A:AnswerDevice plugs directly into a HDMI input on your TV and highly recommend you use the extender ( provided ) to get best signal from your internet router / modem. Problems associated with DIRECTV NOW buffering are related to early development of this service and eventually will be resolved but streaming tv is the future and ALL cable will go away.
I've had better results with the Apple TV device and use the Firestick on my bedroom tv.

A:AnswerI'm not sure if it will work with a projector but it might. If I leave my tv on what ever hdmi I have the stick plugged into and hit the center button on the remote it turns on my tv. It's possible it could do the same with a projector.
A:AnswerLook at a picture of the remote control. The new one is more rounded and has the Alexa speech button on top.
You can't buy the old ones anymore, so chances are its the new one.
A:AnswerDepending on what type of televisions you have in your home, if you have smart TVs then you may not have to have numerous firesticks because smart TVs have the same capabilities for movies/TV shows/apps as the firestick. We have multiple firesticks due to preference because I like the firestick interface compare to the smart TV.
