Yes, they do work. If they didn't work, the staff that reviews the hub entries wouldn't let them be openly publicized. So it seems to me that the problem is with you or your code. Take a look at them again, read through them carefully. If they're in demo's or in the tutorials, then they're probably not plug and play. So you'll have to learn to incorporate it into your code. Post the code where your problems are with a problem description, and then you'll get some positive feedback with the answer your looking for.
