they easily move with your foot. Use almost every day. I can listen to my music while exercising in my basement and having my iPhone in my bedroom! First shelf arrived completely shattered and pebbled. The audio works well but I recommend a headset so you can hear the game as you play otherwise if it is recording your voice and the game volume is up it will have reverb which is not preferable. The ease of use is great. My panels arent very heavy so I only used dry wall screws and they are hanging just fine. You have to shave over the same spot five or six times just to remove the hair, and it isnt a close shave at all. They are the best looking socker socks compared to the UA and Adidas. Although the installation is fairly easy the stand us too shirt.
