    Pros:
    Устройство очень легкое. Специально взвесил, 4 грамма. Размерами тоже порадовало. Миниатюрное. Подойдет тем, у кого ограничение по весу и размеру. К тому же пищалка очень громкая.

    Pros:
    Even thought I gave 5 star rating, the product description states that it takes 2-4s batteries however, the alarm can take only 2-3s batteries and not 4s batteries. The description should be changed. I ordered the product based on the description but failed to see that the photo is different. Usually items are ordered based on the description and not the photos. I will now have to try and sell these off to others.
    Cons:
    The buzzer is loud enough
