Rated 3.4 out of 5 by 16 reviewers.
Rated 5.0 out of 5.0 by Very good purchase I loved the color and it worked perfectly in my kitchen. May 6, 2014
Rated 2.0 out of 5.0 by Very inconsistent sizes, great price, nice finish 175/8, 177/8, 173/5, be prepared. Ended up getting twice as much as I needed for a 14x15 room. Was paying a tile guy to install, I had to run out and get twice as much as needed so they could go through the boxes and get the sizes and color consistency that they needed. I have a lot to take back now. Even after this it was hard to get a good grout line, so I compensated by using a grout that was a similar color to the tile. The tile must be durable, 20+ boxes and not one was broken. I feel like I can't complain because the price is so good, the look is great, but be prepared, this is what you will have to go through. I recommend with reservations. April 5, 2015
Rated 2.0 out of 5.0 by Beautiful, but NOT a good idea This looks beautiful if you look at one tile, however when you start laying it you will notice due to the large size the tile bows and humps up in the center. The corners then lay lower and you get a very uneven floor. Talked to home depot after we started it and they admitted thats how all tile is larger than 12" x12". Not very happy to have put this in our BRAND NEW home, but not going to rip it up either. It has a beautiful look, just don't look at our tiling job too close up. Also, every box we opened had a slightly different size making the final lines look a bit crooked. Great. July 21, 2014
Rated 5.0 out of 5.0 by Really Nice Put it in my laundry room to replace old vinyl flooring looks great and easy to install. February 2, 2015
Rated 2.0 out of 5.0 by Love it but hate it Every box had 3 different sizes it caused major stand still to go through all boxes to get same size .My contractor is a perfectionist .He wanted to return all 43 boxes but we already started project before we started to notice the different sizes.My back killing me from measuring each tile.Going tomorrow to see manager .Unhappy helper.

Rated 2.0 out of 5.0 by Great price but not worth the headache We purchased enough tiles to cover 500 square feet. We were given tiles from many different dates and lots. The tiles are described as 18" x 18" square tiles. They are anything but square. We have a perfectly square room and we had to adjust our spacing with every tile we laid since they were all odd measurements. It looks nice to someone who is glancing but it's very obvious when you look closely. October 7, 2014
Rated 3.0 out of 5.0 by Looks okay but some tiles not cut correctly Purchased 9 boxes. I did not notice that a small percentage of the tiles did not have square cuts until they where installed. The result is that some of the grout lines are not straight and appear to widen from one side of the tile to the other The difference may only be about 1/16-1/8" but it's noticeable to me. July 11, 2014
Rated 4.0 out of 5.0 by Size variations? Not with my experience we have installed about 20 pallets of this tile over the last few months and have not seen a noticeable color or size variation. plus or minus a 1/16 is expected with this size tile and even my new guys haven't had problems with it.
