BetDSI is safe but let's be honest, it's an average book at best. It's touted highly because in Cris family, it pays advertising fees and your funds are safe. Sad, but all it takes in today's climate to receive an A+ rating; hell John would probably give any book an A+ if they paid.

From a long time, regular customer from USA here is my take. Lines are terrible (good 10 cents off on mainstream sports and even worse on international sports than Pinnacle, 365, etc.). The fees are absolutely theft as already pointed out above by various posters. CS is nice but clueless most of time. Casino has already been proven on here to be rigged worst than most, maybe even worst. Some nights they offer live betting and some nights they're just lazy and don't offer it, no consistency.

Good, 24 hour operation so can use cashier at odd hours and funds are safe. All I can really think of in terms of good. Guess site look isn't bad either and easy to navigate.

That is your A+ book. I would say much better options for USA player but not really, all have their flaws and all have gotten considerably worse over time. And if you're outside of the USA no way in hell I would play at DSI.
