This product is definitely designed to fit the round shape of the head, so it was easy to clip on. Since only the part near my part tends to lay flat, I wanted to add volume just there, and this was exactly what I needed. It seems to create a natural volume well. However, it might be loose for those with thin hair, and if you're looking for really big, dramatic volume, you might find it a bit lacking. For those like me who want to add natural volume, this is great.
