An additional note about my previous posts, regarding user @sugarfreedaddy
I want to state here that my problem with him is now solved.
He was unable to send me the module that I purchased, and he was unable to refund me.
I offered that he sends me other modules for a similar value. He did, which means that, I don't really understand how or why, he was in a problematic situation, but in the end he did not scam me.
Happy modular everyone :)
