This is a SwitchBot Smart Lock Pro. I've been using it for about a year. I'm selling it because I've switched to a different manufacturer for my home IoT devices. The front side is in good condition, but there are scratches and dirt on the back side where it attaches to the door. The strong double-sided tape was very difficult to remove and caused some damage. I have confirmed that it works, including connection with the SwitchBot Hub. - Brand: SwitchBot - Model Name: Smart Lock Pro - Included Items: Instruction manual, mounting parts - Color: Black - Features: Remote operation possible
