Blackjack Has Anyone Tried 21Mastery for Blackjack Training?

Hey all,
I’ve been searching for a structured way to improve at blackjack beyond just reading books and forums.
I came across a site called 21Mastery that offers a full blackjack training course — with card counting practice, game selection advice, bankroll management, and more.
Has anyone here tried it? Just wondering if it’s worth diving into.
Not sure if it’s well-known or just starting out, but the structure looks promising.

 

The 21Mastery blackjack course caught my eye too. Just not sure if it’s worth the investment. Would love to hear how it compares to stuff like BJA or Snyder’s material. I actually checked out their free content — looks surprisingly solid. Curious if anyone here has done the full course and how in-depth the simulations are.

 

Been thinking about the course too, need to check out what you wrote

 

I sharpened my card counting skills with the extremely helpful Casino Verit'e from Qfit. The site offers free downloads for you to sample the product before purchase. It includes instructions and drills for a number of card counting strategies, and helps you to develop your very important card counting speed. I prefer Hi-Lo. Card counting is most effective with single-deck games. Far less effective for six-decks or more. You can also practice card counting with the Wizard Of Odds free online game, which allows you to adjust the game rules and has a selection of card counting systems to choose from.
