    Porosity (bubbles)
    There are so many holes! When water gets in these holes and it freezes, the surface of the stone will break off. Placement of hangers is bad, color doesn't match the other pieces I purchased. This is just poor quality and it's not cheap! Never again. Home Depot should consider dropping this company.
      My first order, every M-Rock, I ordered 5, was broken. Took 6 weeks to receive. I reordered again, waited another 6 weeks. Fortunately my order arrived at HomeDepot and all the pieces were good.

          Terrible shipping, packaging was a joke and customer service 3 of the 4 pieces were broke and unusable No help was offered to help move the project along in a timely fashion

          Easy to install
          Each piece was consistently inconsistent in size. The color was similar with each piece. A simple hand grinder was all that was needed to shape pieces to fit where they needed to go. It would be nice to have corner pieces to make install easier. It is also important to note if it is going under something there needs to be room for the attachment brackets. So far, they have lasted through two Minnesota winters without any problems.

            Size and color
            My project needed 89 inches of sill under the window. I purchased 3, because they were advised as being 30 inches. When I dry fit the ledges it was short 2 inches. I checked my measurements and that's when I found that the length of the stone, is only 29 inches. Color did not match the other pieces that I purchased from this company. Quality is super bad!
