I was greatly disapointed in Pergo flooring. We were attracted to it because of its ease of installationand care, and its attractiveness. What we found in practice was something entirely different. The floor is easyly damnaged by everyday occuracnces such as rocks caught in your shoes or dropping a can of soup on it. When we were installing it, just the act of putting it together can damnage the floor pieces. The grove is deeper than the lip. This means that as soon as you tap the two pieces together it will bubble. When I was installing, the light was poor and therefore did not notice the problem unbtil several rows had passed.
My overall opinion; Pergo scraches easily, puts together as easy as legos, but looks about as good when done. If you don't believe me...come on over.
