Over three months I bought 3 of these.  Two for the entrances to the kitchen, and one for the front door (on the inside).  I was afraid that it might not stay in place (which is why I ordered them over the course of three months).  So far, no trouble with them sliding or rippling and catching my feet.  The electronic vacuum has no trouble with the edges, and does a good job of cleaning them.  I'll take them outside for a spray washdown when the weather gets warmer.
