For sale is the latest gen3 AlrterLock. I purchased it late last year and used it for about 8 months. It has been charged twice. All accessories are included. Product Description: This is a GPS transmitter and security alarm that attaches to a drink holder gauge. Unlike AirTag-type devices, it uses an LTE network. Therefore, it can independently obtain GPS information and send vibration detection notifications. You can adjust various detailed settings via the smartphone app, such as the sensitivity of automatic locking/unlocking and vibration detection. It is a multi-functional, high-performance GPS alarm with features such as sending a message to a pre-registered emergency contact in the event of a strong impact, such as an accident or fall. A separate annual fee of 3,960 yen is required for network usage. Please see the manufacturer's website for more details.
