Worst experience, fraudulent seller
Worst experience, ripped me off twice for vcm2. Sent vcx nano clone style first time, did not work correctly. Paid another $120 second time for a full chip style pcb , they sent photos and promised it would work. Sent another vcx style single chip board. Then said it was a mistake and i should return it at my cost over $100 to send back to china. Complete fraud and they know what they are doing. Very difficult to get money back, i am out over $240 now.
