Wsdcam Door and Window Alarms for Home Security, 110dB Magnetic Sensor Alarm, Pool Door Alarm for Kids Safety, 4-in-1 Mode Small Wireless Door Alarms 4Pack

I was skeptical when my husband told me that he purchased this alarm system. Once my husband had them installed on all the doors and windows, (which only took minutes) , they worked amazingly!..they do the job we've had other systems over the yrs that we paid monthly premiums for, ADT and PROTECT AMERICA. The only difference is, you have to pay for the service, monthly, and when the alarm is activated, if the company is unable to reach you, they contact the police or fire depth. Whichever is needed. We basically wanted them so that if someone attended to break in a window or door, the alarm should scare them off.. it is quiet loud. We're very happy with them.

This is a great product for the price!! If you have small children it can alert you if the door is opened and if you don't have an alarm system yet this will give you a piece of mind that no one is able to get in without you knowing! I love it It also alerts your neighbors when someone is opening your doors and windows it doesn't deter if a window breaks but it's a great start to home protection!!

These little things are awesome! I have them on all my kids windows and my doors so I know if they have been left open or if someone comes through my door at night and they are super loud!

I haven't put thesecup yet because I am moving shortly and will use them there. However, I had these in my prior residence and I really did like the option of chime or alarm.

This works really good , my dad has dementia and it let me know when he opens the door.. very satisfied with my purchase..

I use this on the window my air conditioner is in. I feel safer at night knowing i have the window alarmed now.

was challenging to install on a rounded door frame. However, we did it, and it works like a charm. No escaping pets.

we love the alarm 4 pack ,it was very easy to install and the Alarms are very loud ,which is very good

i bought because my special needs son at night goes outside now i have this loud alarm to alert me ... excellent safety feature

there was no chime or second sound option as advertised. there is only a very shrill screeching alarm noise. they are single purpose only, but make it look like the other roducts with a second sound. the plastic is very cheap too, almost brittle already.
