Not worth your time to look at. If you will engage in sports betting, the faucet feature should not be one of your main criteria to look at.

I don't know the reason but maybe you are looking at the possibility of a "free bets" feature? Usually, the majority of bookies are offering that kind of promo but in the form of an event and obviously, there's a period.

There's a free bet promotion in most cases e.g Sportsbet, Nitrogen, etc.
