HIIXHC Personal Security Window & Door Alarm Bell | Wireless Sensor Door Window Burglar Alarm | Pack of 10

Bought these when my toddler started opening doors and now with recent break ins in our neighborhood they’ve brought me even more reassurance. They’re very loud and easy to install I use them on my doors and windows. Great price point for the amount you get!Only con is that I couldn’t get one of them to stick so I had to buy new tape for itAlso I’m not sure why everyone complains about no batteries being included that’s basically with everything you get nowadays. Just order some AAA batteries if you don’t have any already

Bueno

So these were great… for a couple weeks.We got these when our baby was born and just now put them on the windows and sliding glass door. They were kept inside and never exposed to differential weather. I felt so great about having these at first and they made me feel safer…. UNTIL!!!Only one was left! ALL THE OTHERS FELL OFF! It was every couple days we were finding them on the floor or window sill.The worse part is that when they fell the batteries would pop out and our crawling baby got a batterie INTO HER MOUTH!I don’t know if the adhesive that came with them was bad or what but for them to all come off accept one is not good.*They adhered to the windows and sliding glass door and even left some hard to get off residue. They didn’t stick to the alarm itself!*I was saving them to buy adhesive from the store but when she got the battery in her mouth my husband threw them away because it was very scary as they are small batteries and they had rolled under furniture when they fell and she was finding them where we could not see them.I have included pictures of the residue showing that they did stick to the window sill, and a picture of how we kept finding them on the floor, and a picture of the one loan survivor that has stuck well and is doing great. But we wanted ALL of them to work for ALL of our windows not just one.I wanted to contact the seller to inform and ask for a replacement, because perhaps we just got a bad adhesive batch, but I could not locate any way to contact the seller.DO NOT PURCHASE. If you do buy, purchase separate adhesive.I will update if seller sees this and sends replacements and how they work. But seeing as how I have not been able to locate how to contact them I doubt that will happen.

These alarms were super easy to install and they really do work. Loud enough I can hear them throughout the home. Great price too.

Obviously liked the low cost. The quality control is non existent as far as I can see. Even the ones that work are not super loud, but I think will work for my application.. I only need a couple so I am keeping them.

Muy bueno y muy funcional

They keep falling off the wall & window sill. Some started going off out of the blue. Would not recommend purchasing these. Waste of money. They are very loud but misfunction a lot.
