GE SH50246 Personal Security Door Stop Alarm,Black

Peace of mind and gives you a good night sleep. It is everything you need

Purchased this to take with me on a vacation at a resort by myself. Wanted to feel safe at night by myself in my hotel room and this did the job! Light weight for packing in my suitcase. It stops the door from opening, as it works just like a door stop and squeals very loud when someone attempts to open the door.

What a great idea -- a doorstop alarm that requires zero installation. Just add a 9-volt battery and you have an instant burglar alarm! Perfect for apartment/condo dwellers, travelers and the mechanically disinclined. It's also great for interior doors (e.g. bedroom) for an extra layer of security, or as a supplemental night-time alarm for the main entry door and for other exterior doors, especially French and other glass doors. It would be all but impossible to open the door more than an inch without setting off the alarm. From here -depending on your floor surface -- the grip-bottom on the door stop may prevent the door from opening further at all, or would at least require extra time and effort (with the alarm still squealing away), buying you a few more seconds to respond. The hope, as with any forced entry, is that the alarm will (a) draw ample attention to the intruder, who will hopefully flee the premises, and (b) alert you to the intruder, so that you can call 911 and take whatever defensive measures you can. Other reviewers reported that the bottom did not grip their floors. In some cases, I suspect the culprit for this may be an incorrect placement of the battery. The terminals MUST face the small end of the battery compartment, or it will cause the base plate to bow out ever-so-slightly -- just enough to keep it from making solid contact with the floor. (It took me a few minutes of head-scratching to figure this one out.). Once I got the battery correctly installed, I tried it on 3 different wood floors, a tile floor and a linoleum floor, and it gripped like a charm. The only surface I didn't try was carpet. Before buying, I would suggest measuring the gap under your door, because this door stop would probably not work with a tiny gap of less than 1/4" or on a large gap (I'm guessing anything over 1"). My door gaps ranged from 1/2" to 3/4" and this size range was just right. I think one review complained that it was too sensitive. We tested ours to see if it would go off with misc. household vibrations (stomping on the floor, bumping against the door) and it thankfully didn't. The only caveat I'd offer is to be sure to turn off the alarm before picking it up in the morning, as handling it will set it off in a heartbeat. Some reviewers complained that it wasn't loud enough. We found the alarm to plenty loud for our purposes. It's reportedly 120 decibels, which is probably about right. For comparison, a smoke detector is about 85 decibels, a car horn about 110 decibels. As security goes, this is a real bargain for $9 and change.

The product is exactly as described! My door frame is little higher then the Door stop alarm but we put an extra little non slip pad and it works perfectly!!! We have tried and it really stops the door and the alarm sound is loud enough, it makes my sleep nights a lot more relaxed!

I bought several of these for our home and my mother's home. Super loud, and will stop or at least make it difficult for a door to be opened wide enough for an intruder to enter. I tested one out on my husband by placing it at the door he normally enters through. It stopped him, scared him and did just what I hoped it would do. He kind of got mad at me and hollered a few explicatives but it was worth it! We have one door that is on a raised threshold so I set the door stop alarm on a book and the door hits it squarely when opened just a little bitty bit. It's loud - ear piercing loud and that's good as it should scare the bejeebers out of a bad person. On doors that have windows through which the unwanted guest might peer through and see the doorstop, just by placing a light weight towel or papers over it disguises completely. They'll just think your a slob and leave newspapers on the floor. My mom was thrilled with her doorstops. Anything to help parents stay safe is money well-spent. Be aware of how all of your doors open since they won't do any good on doors that open to the outside. The 9 volt battery was a tad difficult to install but I'm not complaining. For my mom I had to write in big letters with a felt permanent marker ON and OFF so she could easily turn them off when not in use and not waste batteries or scare her by an accidental alarm. We'll be taking some of these with us on vacation. These are really great! UPDATE: December 1, 2011 - I have bought several more of these because they are so practical and good at what they do. I've learned to pick them up by holding the sides of them lest I accidentally hit the metal plate on top and hear it's ear-breaking scream. I've taken at least one of these on overnight trips to put against the door in our hotel rooms. It makes me feel a lot safer knowing this thing will scream if someone tries to break in.

I bought this door stop alarm to use on my outside door each night. My wife and I live in an apartment in the city and it is always a smart idea to have a little extra security. As you can tell by the picture that I provided it is a relatively straight forward design. It is about the same size, maybe slightly larger, than the usually door stops you would see at your school or office. If you look at the picture of the bottom of it you will see that there is a piece of rubber on the bottom that helps to keep it from moving with the door when it opens. I have tested it several times and the rubber piece does a good job to keep it in place. However, I have had it slide across the floor one time when I was testing. Since that scared me a little bit, I now use an extra piece of tape on the bottom of it when it is in use. Works like a charm now! The level of noise seems to be pretty darn loud. It is loud enough that when I go to test it before bed, and my wife is near it, I usually get a look of disgust from her annoyance. We can easily hear it from about 30 feet away through a bedroom door. The battery life has been pretty amazing. We have had it for about a year and a half and we are just now having to replace the battery. (hence why I thought to write this review). Overall: This is a great supplement to home security and very well priced! I give it 4 stars simply because of the rubber on the bottom not being sticky enough, but this is easily fixed with a small piece of tape. Otherwise I highly recommend! I have also attached photos! Thanks.
