Probably a scammer. He refused to give the material for the test, asked for a money transfer in advance. Deleted the dialogue in telegram after I refused. The channel is fresh, posts dated March 5. I would not advise anyone to buy material from this man. Because I know from experience that if a supplier has good material, he will never refuse to give a test, and at the same time he will not beg for little money like a schoolboy. Think about it guys.
