10/10 would recommend.
I've tried researching and creating my own treatments, but this is what I was looking for. You can use the treatment as is or customize it according to how you want to brand and pitch to others
Also, reassuring that they're made by a production company that uses these in the real world. I created my first treatment and send it out to a client and got approved. So yeah, these are definitely effective. You just need to find your voice and input that in, then you're good to go.
