Review on Hooshion Extender Advanced Standard Controller by Paul Williams

I didn't give it a star because it's probably user error, but I'm pretty tech savvy. If this didn't work for me, good luck it works for you. It's pretty easy, just slips right onto your antenna and fits snugly. But every time I used it, it degraded my signal, not boosted it. So in terms of boost cymbals I think it's a good deal. I just don't think a mod that cheap would really improve a $1000 drone.
