The stupid metal weight!!! Remove this!!! Rip the plastic case apart with your bare hands (it's not that hard, you just have to work at it for a few minutes and it will come apart) and then pry out the metal weight. Reception goes from 5 ft to about 25 ft instantly. Plastic case snaps back together. Board is 5v 100mA, which is standard USB power if you're able to make an adapter.
