This is a pretty good Mouse. There seems to b plenty of space for charging cord, xtra silicone tips etc. The sound quality can be noise canceling if I have the volume up but with these, I dont need to have the volume up that loud in order to hear everything. The middle of the heel-strike is a little harder than the surrounding area and some people have complained about it, but I havent been bothered by it in the short periods of time Ive spent in them. I just wish there were a little more space between the levels so that my heels fit in better. It took seconds to stick the red fob to my TV remote, the blue to the house phone (which is mysteriously always disappearing,) the green to my sunglasses case and the yellow to my car keys. I wanted something that would protect my Apple Watch without compromising on the styling. The elliptical diamond does pick up more noise, but also feels more "live" than the ML, which can be a bit laid back in presentation. DESIGN : v. I wear an 8 1/2, purchased my size and they fit nicely.
