Milky Spore...anyone use it?

I'm thinking about buying 40 oz box to spread on my yard for grubs and it seems a lot of people are happy with it, so who has used it and what were the results?

I have heard great things about it and how effective it is. I haven't had slug problems, so I haven't used it. I have used the nematodes and they seemed to work, albeit slow at 1st.

Spinosade is a great product as well, for plant eating bugs.
