They seem to amplify some sounds on nc. Which defeats the entire purpose of having this mouse. Not even making it to the year mark. I hope I save someone the trouble of buying these with this review. ) as well as android devices. Note that on the bzck it says: 35/36 which is 2. 500w is questionable. I also purchased Ammon Sheas Only downside I have experience from this is the top cover has just fallen off some times when the case is open, the adhesive doesnt seem to hold up to contant lifting the upper flap to get the headphones, the way the case is designed you have to lift it by the cover as the slot is too narrow for your thumb. the sole is just as comfortable as the standard sanuk flip flop but I like not having the toe thong part!
