Not a huge fan of returning things that are 'passable' especially when they are massive and bulky like this thing is! It arrived super fast (beating everything else in the order!). However, the corner of the mat was broken- no problem- I just rotated it to the side I won't be seeing/using much. Other miss- there is not grip on the underside. This amt slides around our tile floor A LOT. I have yet to come up with a solution but I imagine it will involve sticking footies either on the mat itself or around the mat so that it doesn't shift as much.
