What I really like about this product is the variety of colors of single mosaic sheet. It varies from light gray through different shades of medium gray to dark one. I didn't really needed to mix sheets a lot before tiling. The mix of colors was just fine. The quality is also good. The tiny tiles are attached to the mesh evenly; there were very few tiles I neede to correct. Easy to work with - I put it on the kitchen wall - looks really nice. The only thing you need to keep in mind is that the tiles are very porous so you need to work with the grout timely. I would definitely recomment this product for all fans of glass mosaic.
