Title: Needs periodic adjustment - Change rating to 3 stars
Review: I bought two sets of these mats. They look nice, but you must be aware that they will slide somewhat, so you have to adjust them periodically (perhaps weekly). One would have to nail these to the floor to keep them in place!I initially gave this one star, but have recently tried using them again, and have changed my mind somewhat. A more realistic rating would be 3 stars. There doesn't seem to be a good alternative - I tried the electronic type which measures distance from a sensor. The one I had was very accurate for about two weeks, then stopped working altogether.
