This is a great add-on to the PlayStation Move controller, it fits perfectly in your hand and it's very comfortable.
It doesn't come with any other accessories or charging leads, so you will need your own cable to charge it up.
Syncing with your PlayStation is so easy, connect it via the mini USB cable which is used by all the other controllers and hit the "PS" button, that's all to it.
Please note that this isn't actually an item you "NEED" when it comes to Move compatible titles that requires this controller, you can use a normal controller, but I have got to say that it's not that comfortable having a full on controller in the left hand while holding the main PlayStation Move controller in the right.
Overall it's a solid product and it's entirely up to you if you want to fork out around £20 on it, if you can deal with the normal PS3 controller than this isn't something you will need, but if you feel that it will annoy you then I suggest you get this product!
