Wireless Magnetic Window and Door Security Alarm

Pros: It is a great deal with no doubts: it is very useful and for that good price you will find it nice. Very easy to use, just choose a place where to stick it and ready. it sounds really loud, I can hear it from my bedrrom 3 floor over the door. You can switch it on and off whenever you like, just by pressenig a button. The quality of the materials is good: it really worths it.

Cons: Maybe the turn off button is small, but but it doesn't matter. It is very visible on wood doors, so if you dont want to see it you will have to paint it.

Other: very easy

Pros: Works as described. Came with sticky tape pre-attached to the units. Just clean the wall, remove adhesive strip cover, attach to wall/window.

Cons: On/Off switch would be better on the other side. Alarm audio is very soft. My dog isn't even bothered by it (he barks at everything). Maybe the bad guy will think it's part of a silent alarm or something?

Other: I'd try a different, more expensive model. Maybe they all are crap if you buy this wireless single window/door unit? I don't know. There are others on deal extreme though, just use the search.

Pros: It's very nice and simple to use.
Its inner working is pretty easy to understand, a simple magnet and a beeping speaker with an on/off switch.
Works just fine, the beep is _somewhat_ strong, considering its size.
Probably strong enough to scare off silly thieves.
It won't wake up the whole neighborhood though.

Cons: The magnet isn't very powerful and if the two pieces are too far away it won't work (will beep constantly).
The built quality is horrible, don't drop it.
But for the price it's fine I guess.

Other: Cheap and serves its purpose.

Pros: This magnetic alarm wails a siren when its magnet is far from the central unit.
It is a cheap unit and provides an on/off button. The alarm stays silent while the magnet is within about 1.5 cm from the receiver. It starts to wail if they are further apart.

Cons: The siren is very loud and there is no volume control. This works good for an alarm or for outdoors, but I could not use it for my intended use, i.e. a fridge door alarm (it is really very loud indoors).

Other: It should get a volume control, and perhaps a timer - i.e., it should not sound right away but only if the magnet has been away a certain time. This would make it suitable for fridge door and similar applications where the purpose is not to forget to close something.

Pros: Signaling the opening of doors, windows and doors. Easy to use: attach one piece to the door and another on the jamb. When you open the door will be distributed to the signal. Signal is strong and edgy. He was well-heard.

Cons: Could be done better. Housing few wobbles and creaks, battery compartment lid is kept weak.

Other: Can be used. But it must be memorable to change batteries.

Pros: -Comes with sticky tape -Easy to install -Simple to use -Low cost -Uses AA battery

Cons: -The wiring where you place battery looks poorly made -No indicator if the battery is still ok inside (except to trigger it) -Button for ON/OFF would be better on top or bottom -Magnet trigger needs to be very close (1cm) to main unit and positioned correctly, or might always remain triggered. -Wouldn't mind, if it was even louder

Other: Good for securing a door or window, where you don't want to spend time or money on instalation.

Pros: The product has a feature very good, practical and simple to install. The alarm sound is very strong when fired, but you need to use good batteries so that the sound is stronger, I installed two in my house, one window and another in the central door, work correctly.

Cons: The quality of the product leaves something to be desired.The product comes with not stack as the image looks like it comes with battery, but you can buy AAA batteries good here even for a very low price and still are rechargeable.

Other: I bought two products, the package arrived with a half open, and the missing piece that triggers the alarm, another product came complete. Analyzing the product that lacked the part, I put a piece of magnet stuck on the side door and the alarm and it worked correctly.
