Sungwoo ALARM

WOW this little device is LOUD. Super simple fix to alert us if an intruder enters our side garage door, in lieu of purchasing a more complex security system which we weren't ready for. Not sure how long the batteries will last, but I'm certain this would startle the life out of anyone who attempted to casually enter our home through the side door.

After the set arrived, one of the alarms sounded continuously as soon as it was cut on so it was defective.The other alarm worked for a week or two then it failed as well.

This is simple to use and very loud when triggered. I feel safer knowing that I would be alerted should someone open my door. I have set it off a few times myself which just takes a flp of a switch to shut off, it always reminds me just how loud it is.

Had to modify it (i.e.) make them both higher so the doors didn't go over them without make contact. This is a change this company should make to everyone of these they sell.

Does not fit under some doors... Otherwise, the product is great and serves its purpose!

I think the sound could be a little louder. Also, my doors are elevated so I need to prop them up for them to effectively work.

A great product...especially when staying in motels and hotels!!

Works well and appear to be built very sturdy. I gave one to family to use in their apartment. I only wish it would turn off automatically once released. Great product.
