  • Great Tool
Size: 4 Pack
Easy to install, loud and a great safety measure if you have little children learning how to open doors. It has 2 settings. Chime and Alarm. Both are loud and distinct. I highly recommend this as it is so useful as a safety precision.

  • Great price and works well.

  • Loud and easy to install
Size: 2 Pack
I used it as a reminder to keep the basement door closed. Easy to install and is reliable. I installed it using adhesive, which worked well because the battery door is on the front. It is small, so it fit well. It would be great for burglars, but it is a bit loud for my use. I really like it and will keep it for other purposes. I replaced it with an alarm that has a two volume control. ... show more

  • Not great for sliding doors
Size: 2 Pack
VERY loud, I wish there was a volume option, and did not work on sliding doors which was my main reason for purchasing.
