Width was ok. in the box perform which keystroke you want the button on the mouse to do7. Full disclosure Im not personally familiar with the silicone type cases that are cheaper so I cant speak about the comparison of those vs this case. I like that it has controls on top of the speakers, so I can turn the volume of my music up or down without using my smartphone. These are the ones we landed on that are wide enough for him and he found comfortable. No problem. My size is 38 and if I knew I would take 37 and half. Arrived in like new condition, wrapped in bubble wrap. The cushioning is great and very comfortable. I opened up youtube to make sure it worked, and I was greeted by what you might describe as tinny, shallow sound.
