Home Security Door Alarm, SYCOTEK Home Alarm System Burglar Alarm Window Alarm Ultra-Slim Wireless Magnetic 130 dBS 1 Pack

The package arrived very fast. The items were put inside a paper box with a manual inside. In fact, you don’t have to look at the instruction, since it is simple enough for just a try. It works as pair, a big one and a small one. Once you turn on the switch, you run the alarm into working position. If the pair separated from each other to some distance, 15cm, it will ring out. So, put them on two parts in a line, less than 15cm apart, it will guard closely without your absence. Just simply peel off the sticky pad, 3m, on the bottom and place them on the place. Done. I admire the size and the quick style working method. With it, 4 places in fact, you have your peace of mind now. It is a very great window security device in the market. It is very loud and will definitely scar any intruder unnoticed by man. You have your option to turn it off by clicking the side button. There is a led indicator that will flash when the power is running dangerously low. Good product and ideal size for windows and doors of nearly any kind. Still, I have no idea how long the batteries will run. It is great to have them inserted in the case upon arrival. My apartment is of medium size (3 beds and 2 receptions) so it is not hard to hear the sharp alarm triggered at the far end even those doors and closed between. So, I believe the sound would probably send the burglar out running. But don’t allow the attempted theft notice the installation place from outside, so exploit the points carefully to locate the alarms, which would definitely turn out to be very important and effective in the job.At first, I got a few initial difficulties in finding my ideal location to install them. Finally, I got a way to the high place and stick it there. I should say 4-items-pack are exactly just doing perfectly what I am looking for after comparing the sizes of both alarm and my door/window frame. They are certainly pretty loud to panic a theft but not too sharply loud to annoy someone living nearby. The sticky pads are looking very strongly tight and I hope things doesn’t drop off and go off for the protection. But right now, I would give 5 without hesitation. It saves me a lot!!!!

I bought these alarms and they came very fast in good condition.Excellent value for investment and so simple to use, all you need was to position the sticky pads to your desired places, like door or window frames, bar, bolt, etc., then activated the alarm by switching the on button of the alarm. They already got batteries so just ready for job. The tow sensors didn’t need to be lined up exactly the same level, but they must be pointing to each other, using the arrows for help. It still worked perfectly well if they were slightly in different directions or slightly apart, no problem for that. It will keep silent, but if more degree/further distance were to go, it will alarm out loud for attention. Since it was small enough I found it an easier choice for home security than some others.It’s no substitute for proper security camera, but it’s a very decent alternative pick for home security.

These security items give peace of mind, simple to install and make one hell of a racket when I forget to switch them off and open the patio doors. I have one on outer and one on inner, an intruder would turn on his heel if he activated the first one... great little product and battery still going well after many months in place..

This unit replaced a similar one bought some while ago. Simple to fit and works well. However, this and the other window alarms are sensitive to the type of heat generated by the sun. So overnight security is great but if your windows are usual in the sun, remember to switch them off in the morning! Equally, if you leave them on while away on holiday, a set of three flat batteries and a grumpy neighbour may be your reward.

Really pleased with these, looked at so many different extra alarms after my car was stolen and these live up to the positive feedback already on here.These have been fitted to a conservatory/porch door so far are really loud, if you forget they are on first thing in a morning (i have several times) it certainly acts as a wake up call (including the neighbours!)Would highly recommend if you are after window/door alarms

From the other reviews I had read I was expecting a loud siren, but even so I was surprised by how loud it was. It is plain simple to install and turn on. Then, it does just what you expect: sounds a very loud alarm whenever a door or window is open.It would be perfect if you could turn it on remotely, but I understand it would make it more prone to flaws. Great purchase!

Absolutely quality product.... 👌. In my opinion they are just as good as a house alarm, and far less temperamental... And they are so loud they would deter most theifs.... And having multiple of them means you can place them everywhere 👍👍👍

We bought some other before this but they were less than half as loud as this . For this reason I think it worth the little extra price.It has a full size, good quality 3M adhesive sticker on the back.
