I haven't read it myself, but here are some reviews:

Mason's review (look towards the end of the post).

Reviews by Rolf Slotboom: Real Poker and Real Poker II. Note that the bad score for Real Poker II seems to be mostly because Rolf is disappointed about paying for the same content twice. Since the content is the same you should be looking at the score for Real Poker.

Conjelco has just released a new edition of Real Poker II. I think I remember Chuck saying that the content isn't any different than previous editions, it's just that the book gets a new publisher and gets printed again.

Ed Miller recommended Real Poker II in GSIH.
