We have 1000 sq/ft on our main floor. We tore up the carpet and replaced it with the cheapest laminate we could get at the time (.79/sq/ft) We considered it a temporary measure until the children grew up a little. With 4 kids ranging in age from 7 to 3, and an 80lb black lab we have no scratches and the floor looks like it did the day we installed it 4 years ago. Even the powder room (which gets wet a lot because of the kids) floor has not warped or anything. The stuff we got had a pressure treated bottom and in the powder room the guys used some sort of sealant - what I do not know. 4 guys did the job in 8 hours, mind you they moved fast. Ours was triple strip as opposed to single - single looks exactly like the real thing. Had we known about single strip we would used it instead and would probably never tear it out. I cannot praise this stuff up enough!
