Payments do not always go through quickly and sometimes get stuck (redo them then). This shows the beta nature of this project but progress is being made. Next step is release of an iPhone wallet, which is currently being beta tested.
For those that want to see the tangle graphically, there is this site.
I've downloaded the wallet but haven't really given it a good test run yet, but yes I've heard some buggy issues still present. Very cool graphical example of the Tangle!
