Solid Hardwood, Engineered and Laminate Flooring - Pre-finished hard wood floors - uneven

We are nearly finished with a 2 room addition. One of the rooms is a dining/Florida room which we used DuraWood Prefinished 3/4 in./2 1/4 in. red oak flooring.

While the wood and finish looks nice, the floor is not as even as I thought it should be. Being pre-fininshed and thus not sanded, I did not expect to be able to slide around in my stocking feet, like on my parent's hardwood floor, but I never expected the uneveness so bad that one could possible cut their bare feet with the raised end.

Is this normal with pre-finished floors?

If not, should the installer have been more careful in matching the evenness as he nailed them in? or is this more a manufacturer defect in not having a consisten heigth of board?

That isn't installation. That is bad milling. Overwood as it is called has a maximum spec. It may be this floor is in spec with the manufacturer. A cheap floor has cheap specs, for overwood.

I could have not said it any better than Perry. I may add that if your dealing with builders it is common for them to use "builders grade" hardwood. I almost consider it cabin or tavern grade that has no warranty.
