SwitchBot Curtain for U-Rail 2 / Set of 2 Functionality confirmed. There is some dirt on the rollers from normal use, but they were working perfectly fine until recently, and you can continue to use them. I was using them comfortably, but I am selling them due to moving. Everything in the pictures is included. ・Please refrain from purchasing if you are concerned about small stains that are difficult to see in the photos, or minor scratches/stains that do not affect use.
