UltraPro Personal Security Window and Door Alarm, 2 Pack, DIY Protection, Burglar Alert, Wireless Chime/Alarm, Easy Installation, Home Security, Ideal for Home, Garage, Apartment, White, 45115

Works exactly as expected. Very easy to set up and the alarm is loud enough to get your attention right away. Gives peace of mind for windows and doors, especially for added home security.

Super simple installation! Batteries are installed and ready to use. And boy does this little alarm pack a punch for loudness! Wow!! I purchased this alarm for a sense of more security. I live on the ground floor of an apartment complex and transients are always walking thru the area sleeping under bushes, awnings, and for me, I had one sleeping on my patio. You can only imagine the fright I felt opening my curtains to that situation. I do have an aluminum pole in my slider door, but the alarm just gives me that added sense of security. Its on 90% of the time and my kids now know they just can't open the door without the alarm going off. ( It is placed high enough so little hands can't reach it). I feel it is quite effective and for what I paid well worth the added peace of mind. I bought the pack of 2 for just under $21, and passed the 2nd one on to my neighbor with children!

---04/02/2015 UPDATE--- Amazon's stellar-as-always customer service sent me a replacement 2-pack (and paid for the return shipping for the defective pack). I've had these installed in my flat for about four months now. Four stars because "I like it", but that's because I don't expect anything that it can't deliver. Let's get real: these are rated highly because they're extremely loud and very inexpensive. They're not rated highly because they are advanced security. They're great for guarding against the kids opening something they shouldn't, and they're so-so for using as a door chime (it's much too loud to keep on all the time, but a good defense against small children wandering away). I bought them so I can truthfully tell my insurance company that I have burglar alarms installed, to get a home-security discount on my property insurance. I'll be taking them with me when I move out to another home. I'll say it again: the siren is LOUD. It will most definitely cause temporary (or permanent) hearing damage if you're exposed to it for more than a few seconds at a time. Even the chime (a loud, shrill, electronic 'ding-dong') hurts a bit if you're right under it when it sounds. Even so, if you're truly serious about protecting yourself against burglary or home invasion, then for goodness' sake, spend more than $9. With proper placement, will this startle the bejeezus out of someone breaking in? Yes, but only briefly. Anybody with half a brain will be able to locate the siren within a few seconds, and will probably notice the easily-accessed switch on the side to turn it off. That means this alarm is really only useful if A) the burglar is easily scared off, or B) there's somebody around to hear it and investigate. I knew that when I bought them, and was fine with it. They do exactly what I expect them to, and they do that limited thing very well. They were easy for me to install. I took about 10 minutes with each one, determining the best way to install it on my flat's wonky doorframes, testing tolerances and distances, and installing carefully. If you wanted to install them in 90 seconds each, though, you could easily do that. They come with custom-cut 3M Command Strip adhesive pads. Peel, stick, press, peel, stick, press, done. They use included button-cell batteries. A green LED flashes when the siren sounds to show that the unit is working correctly; it doesn't stay lit. This will probably not protect your house while you're on vacation, but it will keep your smaller children where they're supposed to be, and will likely protect your doors while you're sleeping at night. For $9, that's a pretty great deal. ---12/10/2014 ORIGINAL REVIEW--- Temporary two stars because the speaker in one of the alarms was dead right out of the package. The LED turns on just fine, but no noise gets emitted. The other unit is fine, and works quite well, but what good is a two-pack when only one works? Currently working with Amazon to get a replacement, and will update with a full review once I have a fully working package.

Product Review: This tiny gadget carry’s a BIG PUNCH! Don’t let the size fool ya! It definitely gets the job done, as I have a huge place and can not hear the back garage door, open from downstairs. ITS LOUD! I love that I can turn it off & on if I need to, otherwise it’s loud enough to annoy you if the door has to open/close too much. It’s only a few days old, so I’m not quite sure about the battery life yet. Also, the photos make it look like a perfect and easy installation & it’s is! However the photos make the two pieces appear to be leveled and flush with the door/window frame. We all know doors & DOOR FRAMES aren’t flush for practicality (especially in newer homes). So your mount may not look like the AMAZON photos (realistically) BUT IT WILL WORK... If you’re like me, once you open the package, with the small two pieces & double sided tape... it’s self explanatory, THUS ENTER THE DOOR FRAME LOL. ”MY” mount is not even nor is it flush, but it works. As long as your arrows line up (on the 2 pieces) & they are clearly marked; you’re good. You have about 1/2 inch of wiggle room to make sure door opens & the magnet mount makes contact with the device mount. I had to do it 3 times because I wanted it too appear even & pleasing on the eyes. God help me LOL. Amazon Customer Service: The original order tracking was marked delivered in mailbox per my USPS carrier. However it wasn’t there. I had no idea what happened. I called Amazon. They replaced it the next day with NO HASSLE, simply on my word. To me, that’s worth mentioning! Turns out it was delivered to the model home in my subdivision. I found it & it’s on its way back to AMAZON! This was an EXCELLENT transaction! I’m pleased with the product, SUPER IMPRESSED with Amazon CS & learned my USPS carrier isn’t that bright, but I’ll give him/her time as the area is new. Thanks for reading.

Work great, good and loud.

LOUD. Easy to install, just uses adhesive. However in the two pack I bought, only one works. The one that doesn’t work will sound off when I turn it on but does nothing when I put it next to then away from the magnet portion. That’s the only reason I gave 3 stars instead of five. Fortunately I only need one right now.

And added layer of security in a city apartment for front door and fire escape window at a very reasonable price. Easy to install - less than 10 minutes. Highly recommend.

My other door alarm I couldn’t hear in the back of the house or in my room .. this thing is LOUD like extremely loud. When u open my front door it sounds lik ur walking in 7-11 or one of those corner stores that make that loud BING BONG when u walk in.. trust me ur kids or anybody won’t be opening your door with out u and half the neighborhood knowing it.

Good product as the brand represents little over priced for the brand name.

Simple to install and operate. Value for money..

Does it's job, strong adhesion! High pitch noise. No complaints!

Práctico de instalar y sonido fuerte.

Tone is a little piercing but excellent product and value for money
