The app shows you the battery status of the case and each freebud. If you have average or smaller hands, fingertipping the mouse will lead to either clicking the primary buttons toward the rear of the mouse (meaning stiffer clicks) OR youll continually have the butt of the mouse bumping into your palm when looking/shooting down in-game. My only concern is that over time, the foam rubber can crack from frequent use and over-flexing of the sandal. But once everything is in correctly, then it works like a dream. The silicon straps would roll right off the phone allowing it to fall onto the concrete cracking the glass protector. These shoes arrived a few days earlier than expected which is always nice, but they really were super super big! I expected a product with a better arch support. I will be doing a month review on this phone for more updates. I purchased these as a substitute and I am disappointed. As if there is no noise Cancellation at all.
