Is this $13 Flight Controller for real?
 

I came across this $13 RC Winged Airplane Flight Controller on BangGood. I am just getting back into RC and in the process of building a plane from a big yard sign. I was wondering if something like this will help me get up to speed on a plane that will be a little difficult to start with. (For the record my wife ordered me a trainer kit along the lines of a Kadet, so by Spring I will have a trainer)
Anyway, has anybody tried using something like this. I am on a tight budget, but this is affordable!

Also, they posted a link to this video. Will this device allow this type of 3D flight (By Me) or is it just the skills of the pilot, or the abilities of the airplane?
