I am from Colombia and work at Guangzhou, China, i sold about 25 sets machine to Colombia for OCAMASTER so far, all machines works very good.
I am a major fan of OCAMASTER as I have the OM-F3, OM-K5 and the OM-518Plus. You can call me for technical support if you are from the US; I would be glad to help.
