This will not be the last pair of Fit Flops I purchase so keep on designing new ones. This is the first time I find wireless earbuds with great touch controls. The main advantage of having this is the battery, its outrageous how long it lasts Ive never actually killed it completely and Ive used it 3 8 hour days straight (around 1/4-3/4) and it still had three bars left! Nice arch support, lightweight. Product is great holds shoe no problem! Perfect for around the house or going to the mailbox. so happy with it. Once installed, they look great and feel sturdy. 5 size allen wrench. for those who were around at the time and were affected by this part of the culture, this was ingenious.
