Concrete Floor Leveling Compound

How easy is it to pour/use floor leveling compound? Are results good?What would you like to ask?
I just moved into an older house (1925) that has been kept up very well, but I am looking to possibly finishing off the basement. The floor isn’t terrible, but it is concrete and there are some spots where it is a little warn away where theres some small holes/divets. Although not too deep I feel as though whatever flooring I would use (carpet, laminate) I would feel it be uneven in those particular spots.
I was watching a home remodeling television show and they used this floor leveling compound (after cleaning the floor and priming it). As with anything you watch on television it looked very easy and it left a very smooth & level looking floor.
I was wondering if anyone has experience using any type of floor leveling compound, what I should know, and the results people might have got from using it. Also, if anyone knows roughly how much it would cost me to do my entire basement (30′x30′)
My dad used it once about 7 years ago. I would have been only 8 years old, so I don’t remember much. But that was the first time he’d ever used it, and he was successful with it. By the way, that stuff is called magumpus.
