I am selling a set of two Qrio Lock Q-SL1 (1st generation) units. These were very convenient in the mornings when I was rushing out, as I never had to worry about forgetting to lock the door. I was using them until today (July 15, 2024), but I am selling them because I replaced them with a newer model. Please note that this product requires various settings to be configured via the app. However, the app was discontinued in 2023 due to the release of the successor model, and new installations are no longer possible (please check the official website for details). I was also unable to use the app because I got a new smartphone, but I was still able to use the key-locking function without any problems. However, since it is uncertain whether you will be able to use it after purchase, I am selling it as a junk item. (Original purchase price: 38,880 yen for two units) The items are used as described above, and have been used for about seven and a half years. Furthermore, there are scratches from when I dropped them during installation, as well as adhesive marks and dirt.
