Home Security Alarm System DIY Kit - Magnetic Sensor - Guardian Protector - Window Glass Vibration Security Burglar Alarm for Homes, Cars, Sheds, Caravans, Motorhomes - Price Xes (Set of 10)

The media could not be loaded. I wanted to try these before cleaning the windows of an apt and it is very easy to install. Alarm noise is good taking into consideration the product price. I am very happy with the purchase, and it does provide a piece of mind when protecting your windows or door. I would recommend installing alarms when the area you want to cover is ready, as adhesive is very firm and not very easy to rip off once alarm and receiver are installed (which is a good thing).Thank you

These are exactly what I wanted for the windows in my home. They were easy to install and they take regular AAA batteries instead of the small button cell type the competitors have, which is a huge plus for easy and less expensive replacement. The double sided tape is provided and holds strong. They are pretty loud and would wake you up from a sound sleep. Definitely feel much safer knowing if anyone tried breaking in, they would be scared away. Would recommend!

Works well for what it is and very inexpensive compared to others. But the glue to the magnet is weak and may need additional double-sided tape.Also, the magnet doesn’t always line up to the same spot to the receiver so it doesn’t look uniform if you’re comparing placements. One of the casings for the magnet receiver fell off at one point when the door was opened so instead of 10 units, I only have 9 units useful with an extra main unit.If your needs are simple alerts, this will do. But if it’s for official business or something “life or death” you may want to look for something more sturdy with higher quality. This is definitely the “Walmart” version but works well enough for what I need it for.

I was able to install them on all the entrances and doors that I wanted to 'protect' but as I was installing them, I noticed that the product is very very cheaply made, and not sure how long they will last or work properly. My concerns are the adhesive won't work after a certain period and the products will eat up two AA batteries very quickly. Today is 1st day so far so good but I will have to monitor them.

The media could not be loaded. I like that the product provides easy assembly, using two AAA batteries per unit. It produces a loud noise, loud enough to hear from a far distance. I also appreciate the adhesive that each unit comes with, including extra. I would like to see them available in black or other colors. The adhesive could be stronger, but it works out because you can take them off later without damaging your home.

So cheaply made ,horrible purchase. The adhesive doesn't stay stuck ,the on off switch is horrible n doesn't always work.the magnet inside falls out .just complete garbage!!!!!!!

Just bought 2 boxes (total of 20 units) and 4 came with problem (switch on/off doesn't work, other doesn't work at all and others that even with the magnet didn't stop)... and ordered one replacement.The replacement arrived and... came 3 that didnt work either (2 switch on/off and another that doesnt turn on...)those that works will simply work since is a straight forward device.Quality is poor (can see that is really cheap product) but does the job (those that works!)My suggestion? test all of them once arrives & return defective one asap!

Like that that they are so loud. Used them on obscure windows at ends of house.

The media could not be loaded. The product was easy to install - simply decide where you want it to go, peel off the backing and press down firmly on the Alarm Unit/Magnetic Sensor to attach it to the required surface. Very sticky adhesive on the padded backing which stuck well to the surfaces I tried the product on - approximately 1mm thick. The volume of the alarm is exactly as is shown in the video submitted. The alarm is very sensitive, so the slightest of movements to the door which broke the connection between the alarm unit and the magnetic sensor caused the alarm to sound. The door can be opened normally without the alarm ringing if the alarm is simply turned off using the on/off switch - so there is no need to take out the batteries. As you can see in the video the main body of the alarm and the magnet do not need to be exactly aligned/flushed for it to work. Very good value for money.

Muy práctico para proteger tus ventanas y a un precio muy barato. Probablemente no duren mucho las pilas, pero se cambian y ya está.

This is a simplistic security alarm that can be installed on any door . Based on the type of surface you are sticking it too, you may have to use a glue like Goop and tape it in place overnight with some masking take. The surface that you are sticking it too has to be flat, smooth and clean. Contoured door casing will not allow the sticky foam tape to adhere well enough. It will fall down eventually. So just put a dab of rubbery glue on the back of the tape and hold it in place with some masking tape overnight. This system is meant to scare the would be burglar away with a loud alarm sound once the door has been cracked open. It is a loud ugly sound. I am going to install it in my truck. I have spray painted it black to match the interior of the truck. At this price it is a cheap way to have a piece of mind that something will scare off an intruder when you are not there. The burglar has no idea who is being notified when the alarm goes off and how the system is operated and will more that likely just run away !!GORD S.ALBERTA CANADAGord Scott ,Alberta Canada

A little bit basic but they work fine

Pas terrible. Très gadget et ne fonctionne pas super bien. Adhésif non repositionnable. Et l'aimant manque de puissance pour être reconnu par l'alarme. Je déconseille Argent perdu.
