### ⭐⭐⭐⭐⭐ Great

Good product

### ⭐⭐⭐⭐ Ding Dong
*by B***D on 20 February 2025*

Just works unless the battery is dead on arrival

### ⭐⭐⭐⭐⭐ Works reliably.
*by M***Y on 8 December 2024*

I bought this for alarming a delivery box and it works great. The alarm is a classic doorbell with a good sound level that you can't miss. It offers other tunes like a digital watch from the 80s, but they aren't particularly useful in my view unless you want something easier to ignore. I shied away from another brand as there were a lot of comments about not working after a few months, and concerns over less readily available batteries. This one seems fine. I'll use one of the other units for the shed in a similar fashion.
