Only one side works now. That pair was awesome. Seriously, do not buy this. I was told I need to take off my shoes at the door, I didnt want to deal with unlacing my boots so I bought these for the kickoff feature. I cut a hole in the side of it, then painted that hole to match the brown of the cabinet. Its not too loose or tight. I still cant believe it. This will free up our coat closets in the main level in our home. Of these 3 none produce 3d Positional sound. Im personally using them as accommodating resistance for shoulder press, squats, and deadlifts and they work great.
