Regardless of the type of site you run, this is a must have add-on. I have had the privileged of working with this for quite a while, and I have to say, it is probably one of the smoothest add-ons offered.
The chance to bet on anything, for fun? Surely will keep members around if nothing more than for laughs. For die hard sports site, it is literally integral.
The author is an exceptional guy as well, so I easily rate this 5 starts, wishing it could go higher up.
Well worth the cost BUT make sure choose the right bookies. Don't let just anyone use this because they can abuse the points system by using outcome ratios other than 1:1. When you do more than 1:1 it results in a huge payout. So choose your bookies carefully.
