I love that the mute button is on the bottom side of the mic where it can?t accidentally be pressed. It?s a nice gift but you kind of have to have it agains a wall for the bottles to sit in it. While theres enough width that a narrow foot could slop around in these shoes, they are short in length. I ordered an 8 1/2 to be safe and my foot just barely fits on the surface of the shoe. Perfect hiking sandals. There are many features that I am still discovering, and the applications work seamlessly, so far. The performance outside of this has been good, it would be nice if they did not have this issue with sweat at the gym. Somewhat wide width, but not overly wide for my particular feet. The aluminum body was nice as were the feel of the keys, even through their spacing was a bit cramped for my larger hands. This is important as the product will generally improve.
