Bests & Worsts Reviews from Amazon

While the friction mount on the bottom of the beanbag is pretty darn stable even with stops, starts, and turns I sometimes would find it sliding across the dash. The solution has been to use one of those little 6x4 inch mats sold at Radio Shack or Walmart for keeping cellphones on the dash. The mat is sticky on one side but leaves no marks or glue. I have not had one slide since using the mat. I even bring the mat with me in rental cars. This gives a very secure mount that is very easy to take from car to car.
