super good this product

I needed these alarms to pass inspection after my pool was installed. They worked perfectly and they were a GREAT price. My only complaint would be there were 2 in the pack that would not work at all, however, luckily we ordered this set to have 2 extras. Very loud and they work as soon as the door or window move the slightest bit. Great safety measure for small kids.

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.

Cuando me mudé a la casa ya tenía un sistema parecido entonces le dejé los imanes que ya estaban instalados . En la puerta se me que sirve con un imanes pequeño , aveces los imanes grande no sirven para ciertas puertas En la ventana le dejé también los imanes del dueño anterior y funciona perfecto. Cantidad perfecta por un buen precio !!

Cheaply made

Loud easy to install .Peace of mind.

Nice for security.
