Next time itll probably take half that time as I marked the rails with a black Sharpie dot so I know where I had the rack clamps attached. I mounted this up high on drywall, almost close to the ceiling with the provided hardware, and it works perfectly fine. Its not like bold or intrusive. I ordered this product and attached the little transmitter to the back of my phone. I bought these for my husbands Bluetooth. I tried it in 4 different planes. Youll get audio but it doesnt recognize there is a microphone. The speakers would be good quality bose speakers that you connect with wire. Maybe I just got a bad one. )10/10 would recommend.
