Warning: a scammer has repeatedly sold a defective AR84, first on Ebay in Nov 2018 and in Jan 2019 on Reverb. This seller, located in Pensacola, Fl, either never ships or ships the defective unit. I was the victim in the Reverb case. Although I shipped it back to this seller, he didn’t refund my payment. Nor would he respond to communications by me or by Reverb. Ebay and Reverb had to make the refund in these cases. You can tell he is the same guy, because his ad shows an incorrect first photo of another product. He may try to sell it again. Beware.
