Looks can be deceiving.
He is selling magic. That in itself is nothing bad. Nor good. But the material... if it would be his own creations, or his refinements on other's creations all would be well. But this is not the case. He is selling Card Warp (Roy Walton) for instance.
Or the good old Snap Change (Ed Marlo), the Card from the Mouth (With Bill Malone Subtleties) or the Crazy Man's Handcuffs (Michael Ammar). For 2 Euros.
It's not his material! He isn't adding anything new! He is making money of other peoples ideas. He's a magic parasite.
Now but that isn't all. He also has a free section, basically exposing material that isn't his. Among those: The Penetrating Straws and the Cut and Restored Balloon.
I don't like that, I don't like that at all.
