So, I seemed to have gotten on the father's good side.  He wanted to do a trade instead of paying me for the sensory device forthe kid, so he gave me this. 

Yeah, that's a 500 dollar drone right there.  I have absolutely no complaints. 

The camera was busted, but I can either fix it or replace it. 

Seriously, the thing that I was going to make wasn't even going to cost me 100 dollars.  I'm very happy with this trade.
