This is a set of two SwitchBot Curtain 3s compatible with U-shaped rails. I had them installed for about six months, but I no longer need them due to moving. The included accessories (cables, etc.) are unused. While there is normal wear and tear from the above-mentioned use, there are no noticeable scratches, damage, or degradation. Automation is very convenient. I would be happy to pass these on to someone who can make good use of them. Thank you. - Model: SwitchBot Curtain 3 x2 - Type: U-shaped rail compatible - Function: Smart home control - Connectivity: Bluetooth/Wi-Fi - Compatible app: SwitchBot App
