    The door sensor is very sensitive and the statuses can be recorded perfectly
    The door sensor is very sensitive and the statuses can be recorded perfectly. You can receive the push notification immediately.
    Con: It took me a while to connect successfully because it was the first time that I had tried to use the door sensor.
    But it functions pretty well! :)

    Rechargeable!!! Great!
    It was exactly what I was looking for. I am too lazy to replace the lithium battery, let alone frequent recharging. Thus, I did not hesitate to buy this one.

    Great product
    No extra USB cable included, so the price is lower. Haha, great! I've already had a dozen USB cables.
