The controls are clunky and the direction is awful. Friends gave me flack about mic quality instantly. Very generic packaging and manual. Shondras from Texas, home state of Beyonce. Can?t go wrong with this flip flop. (Also, in the case received, there is no dip in that area - just a cutout. The bass on these is punchy, but is generally weak and teeters off immediately. This rack has worked fine on my mountain bike and I havent had any issues with keeping it on tightly, including a fair amount of trail riding and a fall strong enough to move my handlebars and crack my helmet. I have been searching for a while now and these are the ones. Perfect flip flops in the fit.
