However watch the size. I love the adhesive twist on suction cups. Most Skechers deliver as advertised. I chose the Tile as I read it has the loudest ring. Not loud enough for size, unless u disable dsp mode, (not factory recommended) However the volume and power is almost doubled! Within a few days the replacement product was on its way. Overall these things were a waste of my time. Why spend more $$ its great This mat has raised dog feet & dog bones to run your feet across and its rubber on the bottom so it want slip or slide. All around 5 star buy!
