The typical use of the Ben Wa ball is, from what I've heard, as a tool in order to practice your Kegel exercises--pop them in, flex the muscles, keep tight, all that jazz. As far as that goes, these balls are properly designed for this function and not too difficult to maneuver.

These are very obviously made of gold-painted plastic, and the sheen was somewhat mottled straight out of the box. That said, I wasn't expecting anything amazing for the price.

Very smooth, these go in quite well. Otherwise, they are unremarkable, solid spheres. They're very small, which should be noted, as they may be difficult to hold inside for some people. The small size also adds little to any stimulation.

These balls work as functionally as they possibly could. As simple, solid objects, they don't have much room for error. They're small, so inserting and removing them should not be an issue.

These are made of plastic, so soap and water will do for cleaning. They have no problem with water-based lube. They come with their own storage, so that's easy.

The box is quite cute, though mine didn't have the velvety cushion pictured in the images. The box is subtle enough people that won't know what it is.

These little guys are supposed to be something of an advanced model, so I thought I was jumping into the deep end of the pool. Unfortunately, unlike most reviews I've seen, it turns out I was not the intended audience for this toy in the opposite way from most others--it was near impossible for me to get the bloody things out again! Perhaps they could help some, but apparently not if you're already relatively tight; I had just wanted the muscular workout.
