I wish I had read the reviews before purchasing this product. I have installed many floors, but this was without a doubt the worst experience ever.
You have to beat the thing to death to get it to lock, and even then the surface is not smooth but has a ridge, as if one panel is a different thickness than the other. After getting halfway through the floor, I called Lowe's and complained.
Store manager said they would take it back, along with the underlayment I purchased. Coming from a company like Shaw, I am amazed that this is such a bad product.
Reviewer is in unhappy mood. Please immediately contact the author of this review to discuss bad quality of swift lock flooring and associated monetary loss in the amount of $350. Swift Lock needs to read this review and look into the issue (if any) according to poster's claims.
