Great rack, relatively easy to install. These have the potential to be the best thong flip flops on the market. They look just like the picture, are comfortable and cushy and (selling point number 2) machine washable! I would say there is less than half of the sole material than the original slipper. These were bought for someone else. IF it didn?t come broken I probably would have just kept it so I didn?t have to waste my time returning it. One reviewer added extra washers to get the smooth rounded edge if the nut to be out far enough to cover the scraping blot threads. works well for me. Cons to product to me it feels like it barely supports my stomach its mostly bulky in the front and the description of this product its way off. Pretty expensive for product though but it?s ok I guess
