i do. i can set default bet amounts for quick betting and i can check the box for "same amount for all bets" which enables even quicker betting.
i like their cash that i earn too. i earn more loyalty cash thru fanatics in less time than i was on draft kings and i was betting higher at draft kings.
each friday they do a fanatics cash drop. i don't always get something but at times i will get $10 or $5 for free.
Cons: their lines can be higher than other sites and they don't have single number spreads. there is always 1/2 added to each line (1.5, 2.5, 3.5, etc.). if you like betting -1 baseball, don't play there.
they pay just as fast, at least for me, as the other domestic books
