You have to pull back on the ear pad material to get the screws back in, and tighten them, but it was a pretty easy install. She likes how soft they feel and says the size Id ordered fits her. :) The boning is sturdy and I am still able to move around for my normal activities. All in all, I highly recommend this mouse. So, Im happy, but must wear thin socks. The order was shipped directly from China. Pads look great, feel very comfortable and are super easy to install - couple of minutes. I only use these during my approximately one hour commute, so about two hours a day, four or five days a week depending on the week. It did not roll down on me. Only con I must say is that they easy get knocked off me ears when I remove or put my face mask on, other than that I love these little bad boys.
