These slides are very cute. Im still waiting for the replacement to be delivered. Schweißresistent. It doesnt slip/flop off when opening and closing like others do. I cant speak to longevity at this point, but WOW! When Im working, I stand cast a shadow on the desk because the ceiling light is behind me. Ill get back to you in about a year. This product reorganized my kitchen by clearing a cabinet and easily revealing all my herbs and spices for easy use. I actually got 2 to go next to each other. Comfy to wear & perfect for the summer.
