Oh my, love this product. 
We had a nasty, useless space under the stairs.  Hubby created custom shelves, painted, and installed this flooring.   It looks so good I don't want to put the door back on!
We used the Floor Pops primer, too.  We laid out the pattern before we started installing, to match the "grain" as much as possible.  Tiles were easy to cut and install.
