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.
I found the OM-K5 is quite easy to use, even though I’m new to this part of the field. Its default settings make me worry less since the machine is doing all the work and I’m even achieving 50+ IPhone repairs per day now!
