DraftKings offers the most sports and contests for beginners only when you are just starting out. I am a daily user and have never had issues getting paid. The fastest method is PayPal, or get it put on your credit card. Checks take the longest, but DraftKings tells all players that a check could take three weeks.
My only issue is customer service is not great, and the badge system for player levels should be improved so someone who is an expert isn't playing IU contests with casual players. Otherwise, I think DraftKings is the best DFS (Daily Fantasy Sports) site and have recommended several friends who weren't disappointed.
Bottom Line: Yes, I would recommend this to a friend
