Has Anyone Used This Grass Seed? [WATCH]

With spring and warmer weather finally here, it's time to start throwing down some grass seed. I've been thinking about this product called Hydro-Mousse spray on grass seed. It looks like it works pretty well and I've seen mixed reviews. One guy said it worked terribly and another guy raved about it.

So, I'm wondering if there's anyone that has used this and had success.

The area we want to fill in is on a slight incline so I'm worried that if I use just regular seeds, they may wash away with the rain where as, it looks like this stuff helps it "stick" to the dirt.

If you've used this, let me know what you thought of it.
