If you want to buy the interface from that person, be careful, he says it is lifelong but it is not, he says that the version you bought is not current, creates a new version and wants to sell again for that.
I had bought it with the promise of being "lifelong" and today he wants to charge me for "a more current version", there are no more "updates" for the one I bought. lol
If anyone wants my Skype conversation with him I will make it available.
L2NPHRN INTERFACE I DO NOT RECOMMEND. -1
