Very fast

This is a very good product. The taillight is bright, and the alarm is very loud (it's advisable to test it outdoors). The remote control, which includes a battery, works well. The braking light's functionality still needs to be assessed. I recommend it.

This is a small, convenient alarm. When activated, it emits a brief, low-pitched "BIIP" sound. If someone continues to tamper with it, the alarm will sound very loudly. The remote control can also trigger the alarm to help you locate your vehicle. Additionally, the remote controls a red backlight with three modes. In the dark, the light will automatically shut off when there's no motion and reactivate upon detecting movement. It's well-made and suitable for use in various situations where you need to monitor for unwanted activity.

The product was shipped very quickly. The product itself is great. I highly recommend it. It's a high-quality and very useful gadget. The alarm function works well to prevent bike theft when I briefly enter a store and don't want to lock my bike. The battery lasts a long time, about 3 weeks from a single charge, even with 2 hours of daily use.
