Seems all radio stuff on ebay these days is either "Untested" or "For Parts Only." I realize sellers have to protect themselves from parts swappers, but "No Returns" does that.
And the few that do say they have tested the item usually have no coax showing in the pics. Makes you wonder how long they had the mic keyed with no antenna before reaching the conclusion, "Transmits great."
They do that to try and eliminate returns. It doesn't always work, though. You'd be surprised how many eBay return cases I have won. eBay knows bullshitter seller techniques.
