Wireless Home Security burglar alarm, Magnetic Sensor Door Window Alarm, Super Loud 110dB, Pool Door Alarm for Kids Pack of 4

we have a 4 year old grand daughter that we don't go out in the yard by herself, as we have a pool. Installing these alarms are very simple as they are wireless. They are very loud for their size, with a simple on-off switch that we turn on when we have our grand daughter over. This is an inexpensive gadget that does the trick, and enhances safety.

Very loud alarm and simple to install. Put the included batteries into the alarm, and then stick them on doors or gates with the included two sided tape. It can be flipped upside down to install on right or left openings. It has an on/off switch if you need to turn it off for a bit. I don't think it has different modes or settings. If it is turned on, and you open the gate or door, you get a loud blaring alarm. No bypass switch. I have these on my back door and another on my pool fence gate as a layer of safety for having little ones near water.

These alarms are VERY loud which is great, and they're easy to install EXCEPT for one thing...... If the window/door is flush with the frame it's a snap to install. I did 12 windows in about 5 minutes. However, I had to put these on 6 different exterior doors. Since one piece goes on the frame, and the other piece goes on the door there is a problem. My door frames are not flush with the wall. I think very few doors are. So I had to use extra mounting tape to make them even with each other. I'm not talking about an extra layer, I'm talking about close to a full INCH. Luckily I had a large roll of permanent outdoor mounting tape already, which I ended up using for everything and not using their mounting pads at all. Another issue with their mounting pads is if you remove it from the frame of your door or window it takes paint with it. The outdoor mounting tape is more reliable PLUS you can remove it with no damage to the surface. I bought the Scotch brand. Other than that I'm pleased and feel much safer now. I put them on every door and window in the house. Just know that you're probably going to have to modify one of the pieces when you install them on regular doors.

These are great and very loud. Batteries last a long time. Actually purchased more

I have been using this product for the past six years. I decided to order two more packs so that way, it will cover every door and every windows in my house even though I have an alarm system. Most of the most burglary does not go through the door, they will go through windows versus front or back door and if they go through the windows. With this Little alarm system you please turn in your windows it is extremely loud and wake you up and give you time to prepare. The packages come with 4 alarm and battery included, I personally did not use their adhesive tape, I ordered my own 3M heavy-duty tape and it never fall off. I also made a video to let you hear how loud it is. Good luck!

The door close warning mode has no delay at all. The alarm starts going off immediately when you open the door. This mode is supposed to help when you forget to close the door. Not go off immediately.

!0 minutes to install all. And volume is perfect. Could hear throughout the house.

The best thing about this alarm is it works on my rounded door frame just fine. A nice heavy adhesive tape is included with each of the four alarms and it sticks the two parts very firmly. Also, batteries are included for each alarm. The sound is loud and should startle anyone breaking in. These alarms are far better than what they had at Home Depot. I couldn't be more pleased! They came quickly and were well packaged.
