This has to be a very different version from the current revision.  My SwiftLock laminate floors are solid and non-flexible.

Words cannot express the frustration I encountered using this product.  I should have thought twice when I observed three open boxes and individual pieces everywhere at Lowes, but I could not resist the sale price and so I bought three boxes of Temple Oak to cover a modest 42″ by 14′ hallway.  Here are the problems I encountered:   

1]  Either from poor machining or warp-age in transit or something else, VERY FEW pieces actually “SNAPPED” together.  More often than not the grooves would not align or the piece was not square thus preventing the grooves from aligning.
2]  It became so frustrating that the temptation to tap here and there with a rubber mallet was too much to resist.  BAD MOVE.  Any attempt to use any tool on the laminate will only result in damaging the groove and further frustration.
3]  The video technique of lifting and snapping each new piece into place with gentle pressure is a crock.  Doesn’t work – won’t happen. 

After five hours of what should have been a 60 minute job, I quit for the night.  I have one more row to go.  I managed some success by cutting a small end off a larger piece.  This I used as a buffer to tap with a mallet.  It does the job and forces the pieces together where possible.  I say where possible because in some instances, even this won’t work.  I was also occasionally able to clean up some of the grooves with a razor knife.  Luckily I bought about a third more than needed so I hope to get enough working pieces to finish the job.

I am convinced the open boxes at Lowe’s were the returns of frustrated customers.  
I WILL defeat this product in the morning and I will have a beautiful floor.  But if you read this before you buy – TRY ANOTHER PRODUCT.  This stuff is a recipe for the nut house.
