Review on Bingfu Universal Amplified Adhesive Receiver by Justin Early

I installed this in my car and was hoping for better reception because I scratched the antenna (fine etching on the rear window, parts not intended for defrosting) when trying to get the bad tint from the previous owner to remove. The radio still worked, with noticeable reception problems. But when I switched to this product, it was 10 times worse. So I opened this thing up and it didn't make any logical sense. The antenna in this thing was an etched circuit board that wasn't even connected to a power supply, resistors, or anything else inside the case. The only thing that worked to get any reception at all was touching the pins on the circuit board to bioelectricity from my finger!
