DC especially has really impressed me over the years. Last, the headphones are sensitive for any digital pianos to generate sufficiently loud sound. It was used! Also wasn?t getting my shoes very clean very well, some other person said the washer did a better job. I got two of them and hung them opposite each other at opposing inset walls. Day 2 I was still convinced they were made wrong and the right foot was actually uncomfortable, however, I kept breaking them in and sure enough they are now so comfy. I thought that was weird but shortly after witnessed the thing vibrate my cell phone off it little by little. Happy I did not have the opportunity to size up because if I did they would be too big! It should only go off when "Alert" is clicked from the phone. The dimensions of the completed assembly near the floor, including the mobile base, are about 39" x 27" (vs about 27" x 25" for the DeWalt).
