I used them for football last year. First time. No problems. Hung lines a little later than they had in the past, according to other players, but I liked having -107 locked in on Monday morning. Good software, some variety in NFL and bigger college game props.
Most important -- very easy to transfer in and out. Paid out after the Super Bowl with no problems. I used them a little bit for NBA, but not much.
I'll keep a balance there this season because of the reduced vig.
Hope this helps.
