## Description

ULTRAPRO AUDIBLE WINDOW AND DOOR ALARMS — SIMPLE HOME SECURITY ALERT SYSTEM The UltraPro Audible Window and Door Alarms deliver an easy, cost-effective way to monitor entry points and deter unwanted access. Designed for homes, apartments, dorm rooms, offices, RVs and campers, each alarm emits a powerful 120-decibel alert that helps discourage intruders the moment a door or window is opened. Installation is fast and wire-free. Use the included double-sided tape to mount the alarm and magnet in minutes, with no tools required. When the door or window separates the base from the magnet, the alarm activates instantly. An easy-access chime/OFF/alarm switch lets you choose a gentle chime for daily monitoring or a loud siren for security situations. Beyond doors and windows, these compact alarms work well on cabinets, drawers and interior spaces where awareness matters. An LED indicator alerts you when battery power is low, while four included LR44 batteries ensure out-of-the-box operation. With straightforward setup and dependable performance, UltraPro Audible Window and Door Alarms provide peace of mind without complicated installations or ongoing costs.

Review: Excellent and Easy to Install - This alarm system was very easy to install, and it works exactly as expected. The alarm is loud enough to alert everyone in the house if a door or window is opened. It’s a great, affordable way to add extra security without complicated wiring or professional installation. Great value for the price!
Review: Worth every dime! - 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!

### ⭐⭐⭐⭐ A limited alarm that provides limited security very effectively.
*by J***E on December 10, 2014*

---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.
