I've had a few goes with them but dont use them much. I tend to do kickboard work to help with kick more for pretty much the same reasons

As other people have said, you can use them either way up, depending on what you are trying to do, but generally I was always told to have the smaller side at the bottom, as this more accurately matches your leg position during your normal stroke and also if you have the tendency to over-rotate and so wobble down the pool if you have the bigger end underneath, pushing your legs too high.
Of course, this may be incorrect, but it was what my swimming teacher told me at our last lesson, and someone else told me the same thing.
They are useful to use from time to time, because if you wobble down the pool, it can indicate that your arm technique isn't quite right and your stroke isn't as efficient as it can be.
