You have everything you require. Simply excellent.

The device functions, but is missing a rubber pad. I'll consider giving a five-star rating if the pad is sent. Currently, my rating reflects the fact that the device is unusable without the rubber pad.

The delivery time was very long, at 111 days! The alarm arrived in a standard envelope, with no protective packaging, but everything was undamaged and functional. The build quality seems decent. It included batteries, which is a plus, as some sellers don't based on customer feedback. However, the alarm is very loud, like a real one, so it might be a shock to wake up to it, or annoy people nearby. I recommend this product, but use it with caution!

That's incredibly loud. Excessively loud. Similar to the sound of a store's security alarm.
