The tiles snap together but need a little bit of force to mate together. A gentle hammer tap or a rubber mallet would make your job easier. You can cut the tiles with scissors with a little bit of effort. For a cleaner and easier cut use a dremel or hacksaw. I used the tiles to level out the floor of my tool shed which worked out nicely for that purpose. Quality seems good for light use, but unknown if it would hold up for a high foot traffic area.
