I've been using it since 2012 mostly on the tablet and I'm a believer. I actually went to Georgetown and the guys gave me a little tour of the HDW operation and was seriously impressed.
The guys in charge are committed to a good product and have some huge foreign bettors who use their data daily. I was a little dubious at first like with using any new figure but after a few weeks I became a convert.
I don't often give product endorsements here or on twitter but I'm a happy customer of HDW and RsPos and think you should give it a chance. I know it's helped my game
