Its a good product you just have to make sure that concrete floor is very smooth, you will have to find find low and high spots with a straightedge. If you read installation specs you will see that the floor height should not rise or drop more than 1/8" over the span of 4'. Wood floors you can sand it down, with concrete you have to grind it down and that can be messy.

That said don't use self-leveling patches or what's ever, because you gonna need a truck load of that...keep in mind the floor don't need to be level, it has to be smooth and when it comes to basements the floor can be a bit rough in places.

I would go with a good quality engineered floor instead if the concrete floor a bit roughed up or in general it will feel much better if you plan to spend time down there or have kids playing.

Good luck
