"Bought my Rigexpert AA230Zoom from Gigaparts & it had a problem. So I sent it to the Gigaparts Auth RE repair center to be repaired. First they never acknowledged receipt of the unit, then they had it a month & told me it worked fine. They sent it back & I found MY repair/issue letter still in the box, completely untouched they never read it, no repair tech explanation in the box and my expensive AA230Zoom still doesn't work!"
