Review: Simple Yet Effective Door Alert - Added this little device to my side door about 3 weeks back as an extra security measure and it’s doing exactly what it’s meant to do. The setup literally took 2 minutes - just stuck it on with the included adhesive strips after popping in some batteries. The volume is plenty loud enough to hear throughout the house when a door opens. Been testing different positions and found it works best about 6 inches from the top of the door frame. The mode options are handy - switched it to doorbell mode during the day and alarm at night. The adhesive is holding strong even with frequent door movement, though i wiped the surface with alcohol first for better stick. One thing to note is that the battery compartment is a bit tricky to open the first time. The sound is crisp and clear, not muffled like some similar units ive tried before. Had to adjust the alignment once because it was giving false alerts, but hasnt happened since getting it positioned just right. The plastic housing feels decent enough though not super premium - but at this price point it’s fine. Really like how you can switch between instant alarm and the gentler door chime depending on your needs. The low battery warning started after about 2 weeks of heavy testing which seems reasonable. Only wish the mounting bracket had some angle adjustment options for different door setups.​​​​​​​​​​​​​​​​
Review: Great alarm system! - I really like this alarm! It’s easy to set up, loud(!), and works well for keeping the dogs and kids in our home. Purchased not really to keep people out, but to make sure our toddler wasn’t leaving the house to visit his best friend that lives across the street now that he can open the door independently.
