Touch Sensitive Anti-Theft Window and Door Hanging Security Alarm with 120dB Siren

Pros: -Does exactly what you think it does .
-Build quality is good .
-Very loud .
-Good packaging .
-arrived in perfect condition .
-Works fine with the SKU 6390 (BTY 280mAh Ni-MH 9V Rechargeable Battery)

Cons: -It "tweets" when you turn it on .
-It is impossible to turn it off without triggering the alarm (just for a second) .

Other: Good item , i'm happy to have it.

Pros: - Loud enough
- Wil wake you from your sleep if it sounds wich is the general idea.
- Good price
- Useful
- So easy to use even my 6 year old sister knows how to use it.
Just toss in the batteries, hang from the door handle and turn it on.

Cons: Not so much cons but it could be a bit stronger built although for the price it has the material is very good.
It would be useful if it could be turned on and off from distance with a remote, but then again, that may elevate the price.
May not work if the superfice is too big (for example a big garage door all made of metal) it will sound if the area touched is near to where you hang it but if its too far away it may not -sometimes it does, and sometimes it doesnt-; I think that might be solved by buying 2 of them and placing them in separate parts to cover a larger area. If you are covering a small area, such as a normal door there is no problem at all.

Other: Good build, very useful, easy to use, does no more and no less than its intended to, overall good price.

Pros: i tried one. very loud,very good package, all my friends asked me to buy one for them,finally i bought 8 of this item, we all loved it. arrived in less than 14 days

Cons: i dont see any cons, may be the place of the battery 9v is a little small. but it is not a problem.

Other: buy it, if someone touch your door or the chain,this alarm will go on and will not stop before the thief go away.
