## Description

Review: Recommend - Works well. Very loud and attaches easily.
Review: Works perfect for our doors leaving to pool! Great Product! - These alarms are great and exceeded our expectations! We just installed a swimming pool and our city requires to have some type of us door alarms for any door leading to the pool, so did some research and came across these on desertcart. They work just as described and are perfect our doors leading to the pool. The loudness and volume level are perfect for what we need. If a door is opened and we are on the other end of the house or upstairs we can still hear them. The battery life is perfect and so far have lasted all season. The adhesive that came with the product perfectly allowed them to mount to the door and frame. The city inspector really like them are and gave us a seal of upperable for our permit inspection. The keychain remote is also a plus as it allows us to activate or deactivate alarm when we're outside. We like these so much that we also added them to our garage door and to my hazardous chemical cabinets in the shed. We highly recommend these to anyone wanting to add a nice safety feature to your doors.
