Hi Ive been wanting to ask this question for a long time but I have two kids busy busy.

I have a Novag Obsidian that is supposed to have 8900 half moves of opening book and it is also supposed to let you know when you have made a move out of book or book has ended. It is actual supposed to stop you from making another move un tell you tell it go !!!

it does none of this anyone out there have one of these maybe Im missing something.

Thank you all
