I returned them without any issues. For whatever reason, Anker decided not to make the bottom 100% flat like the top so you have to do a slight balancing act if youd like to set the case right-side-up. Like I said, I do just repurchase them because they?re so cheap, but there have been times when I?ve bought them and one of them will come broken. These are a tighter knit material and are comfortable for my long shifts. Use to have a pair when was in uni but sadly fell apart after a couple of years and these have been the best so far . The holes at the bottom allowed the water to exit the shoe well and although a little stiff the first time wearing, softened up once worn and sitting in the sun. These headphones are EXTREMELY comfortable for hours on end, even whenever Im wearing glasses. ??????Other than that, I love it! Will continue to buy these slippers. Works great I use it to put hanging baskets in my kitchen it has worked so well Im going to get small hanging plants to try those
