Brand New high quality replacement receiver spectrum Ar6210,,any defects can be exchanged or refund.
I purchased one of these RX together with an AR7000 RX. They look like Spektrum units have Spektrum moulded into the case. I sent the units to Horizon Hobbies for validation.Turns out they are counterfeit in the words of HH.
I shall of course be returning these items for a refund. Just goes to show caveat emptor
