Interested in hearing a bit more about this book myself.
No firsthand experience. Do know that they’re new … less than a year old I think. Obvious that BetShop is “euro-centric” with regards to their offerings … so, I suppose any detailed answers with regards to this book would depend on what sports you play. In other words, American football bettors might be better served elsewhere (Canbet for example); while international sports players may find plenty to their liking at BetShop.
BTW: As per BetShop terms and conditions, they’re not available to USA residents.
