I can imagine that about half the people that run across this item have no clue what it is and are trying to figure out what the hell to do with it, and the other half are looking for this exact item knowing full well their intentions with it. I'll do my best to review from both sides.

If your new to the sex toy/BDSM scene then your prob thinking to yourself: "okay I'm pretty sure where it goes, but how do you get it on? Then what do you do with it?" The broad term for it is "cock cage". This is a pretty tame version considering that some are made from metal rings and not rubber. This is great for people who have not experimented before with any kind of CB (cock/ball) device. The largest ring goes on first, around the cock AND the balls (1 ball at a time), then of course the rest of the (limp) cock gets strung through the rest of the rings. The back of the package gives pretty basic directions which is always welcomed. DO read and pay attention to these, we always want to be careful when playing the jewels! From there, it's up to you how to play! Add some lube and go for the holy grail or just attach a leash to the little metal ring at the tip and lead him around like a good puppy. Pull on anything connected to a man's cock and trust me, he'll follow!

For the veteran players: this little device is very tame as I mentioned above. If you have been in the scene a lot and have not done this type of CB play and want to increase your confidence before getting into the heavier cages, this will do the trick. On the flip side, if you're into true chastity or torture, this is not the right item for you. The ring at the tip is very nice for your leash and a convenient tie point for some very interesting bondage (tying the cock/balls to the feet while making them walk is one of my favorites!).

The bottom line: the material of the rings and the spine are soft and flexible and not very intimidating which is great for beginners. If you're experienced and beyond, then you might want to find something more substantial. I don't think a kind Mistress would even be pleased with something so soft for training reasons. Keep in mind that if he goes soft with it on, then it would probably quite difficult to keep on. Also, if he is very large this will not fit him.
