I'm very happy with these garage floor tiles. I covered my 2 car (20 x 20) floor with them in a checkerboard pattern. Installation was very simple with the click locks on each tile. I was able to easily cut them with a handsaw for inside corner cuts or my small circular saw for rip cuts along the wall. Do leave some room for expansion. These tiles lock with six loops on each side, so the connections are very strong. Undoing a tile in the middle may be a challenge if you have to remove one without damage. The look is so much better than my bare concrete. These tiles are solid and sound a little hollow when you walk on them. I suspect the floor isn't perfectly flat, and tiles are not bonded to the floor when you step. It's easy to roll my full tool cabinet on them, and easy to keep clean with the blower or mop for rain drips. I wish there was a edge pieces for them, but at a half inch high, there's no problem rolling the car in or out. I'm very happy with the new look.
