Bonetooth Necklace is a good item, and I've been getting it much more in recent games with Rengar (to devastating results). Having said that, its effectiveness does rely on knowing how to use Rengar well. So it's basically just what Oscillation said, learn how to use Rengar properly first.

I basically only ever jungle Rengar, so perhaps my rate of gaining stacks would be a lot higher than if you were top lane with him. I don't know what you intend to do with him but just keep that in mind when you consider the purchase.
