Little calculation: if you use your wards 2 per 2 and back immediately when the last 2 wards expire, it's like you have a generation of 8.3 gold per 10. Using the wards 1 per 1 is a generation of 4.17 gold per 10. In the 1st case, it's way better than any GP/10 and the second case is equivalent to lucky pick and a bit lower than philo stone. Personally, I often use 2 wards at the same moment when I support so I guess I'm gonna love it.

Other calculation: each full refill of this item gives you 300 worth of gold. So the more you refill, the more gold you get (in equivalent).
