Hello, first time posting here, and just like the previous post by napoleonbp, I am still quite hesitant on purchasing this because $ 600 is a big a deal of money, I have some questions if you don't mind me asking. 1. Will this work in any casino around the world? 2. Personally I haven't been at a Brick and Mortar casino before ever, can you still recommend this? 3. Will this work on online casino? 4. Any kind of warranties for this? 5. And lastly, is this difficult to master or grasp at all? Thanks and I hope you can attend to my queries ASAP as I would want to give this a try right away.
