I have five different sets of interlocking tiles, one thicker, one thinner, two of the same thichness as these. Norene of the others cost as much or have the rubber top layer. These are by far the best, at least based on a moths usage. I initially worried that they might begin to delaminate from resting heavy weights on the (e.g., my deadlift loaded bar), but so far, there is no signs of this. Traction is good, but still comfortable for unshod feet. A great value in a good mat.
