It was highly annoying to wrestle with the Tune2Air Bluetooth with other Bluetooths you wanted. 5 in heels, and these heels fit me perfectly in a 5. Received a lot of comments about them over the summer. Can be used as formal or partywear. I have also used it as a laundry bag during my travels. If my review of the Kingston HyperX Cloud Stinger has helped you make a decision about purchasing please give me a postive rating. comfort has been fine so Im probably being too picky! I will update my review as I get more usage, speaking of, I need to go change my review on my old pair. They were really cute and the perfect color but I tripped 4 times in the 2 hours I wore them. I am pleased with this purchase.
