This is a terrible series! Don't buy it!
Mmmm. You're still here, eh? I guess my plot to keep these miracles to myself has failed miserably. In that case, I'll come clean.
STRONG, STRONG, STRONG, STRONG!
I got the whole set and every DVD has worthwhile material on it. But if you're on a budget start with volume 1 or volume 2.
Osterlind is an innovative developer of mental effects and a talented performer. Not only that, but he's a good teacher too.
Most of the effects require medium to high skill levels to perform really well. It's not that they are that demanding in terms of dexterity or other physical skills. Like all of mentalism, it's your persona and your skill as an entertainer that matters most. For some effects, however, you will need some specific skills (like a Zarrow shuffle or equivalent) while for others you might need to purchase a prop separately (like a Himber ring.)
As with ALL magic videos BE SURE TO WATCH THE PERFOMANCES MULTIPLE TIMES BEFORE YOU WATCH THE EXPLANATIONS!!! Once you know the secret you'll never again be able to look at the performance through the eyes of the spectator. That's especially important in mental magic.
