Works Great - Very Loud
The alarm is great! It works as described and it's easy to install. It didn't came with batteries, but I had a pair of AA ones in the house anyway. The two pieces don't have to be extremely close for the alarm to work, as pictured. The remotes are also better than expected. Good build quality and a few meters of range (they have batteries inside). When using the remotes, you get audio feedback from the alarms, which is great if you want to arm it from the outside, for example, and you can't directly see the alarm's flashing LED.

Nice quality.
Nice bit of kit, especially the quality of the key fobs. fitted in seconds and works great. Maybe expected the alarm to be a little louder? but for the money a great little easy fit alarm! worth the money? Yes!

Nice and loud
Go onto YouTube to find out how to pair more than one alarm to other remotes, it's easier that trying to follow the instructions. I have 2 alarms that now work with 4 remotes for my garage.

Does the job rather well
We had an intruder incident a couple of months back, after which I haven't been able to sleep well. Installing this has helped with that.

Estaba buscando una alarma para mi piso, y despues de ver varias alarmas, con sistema de comunicacion de intrusion, via wifi (internet), o por GSM, con sirena, detectores de movimiento, grabacion de imagenes, etc, mi mujer me dijo que lo veia todo un poco complicado, asi que me decidi por este sistema, sencillo y practico. Es cierto que para una vivienda en las afueras o un chalet, se queda corto, pero para un piso centrico, donde hay vecinos, y que cualquier alarma sonora se magnifica, es mas que suficiente. La alarma, a pesar del reducido tamaño, suena fuerte y hace desistir (que es de lo que se trata) a los posible amigos de lo ajeno. Y con los 2 mandos a distancia, puedes activar/desactivarla desde dentro o fuera de la vivienda, yo vivo en un segundo piso, y desde el rellano de la entrada al portal me funciona. Sencilla de instalar, no necesita de tornillos, simplemente con la cinta adhesiva a dos caras. Por lo tanto, mi impresion es la de que, por un precio minimo, obtengo una tranquilidad, que no tiene valor.

The alarm controls remind me of key fobs. Trying to put a remote on your keyring might be challenging because of the very narrow space at the top where a keyring could fit, but I'm fine with just keeping it in my purse or pocket whenever I'm leaving or entering the home. The alarm is very loud. I think this is a great purchase for the price.

Je cherchais une alarme assez bruyante, facile à poser et à bas prix : cette alarme répond à toutes mes attentes. On peut l'installer avec du scotch double face inclus dans le paquet donc la pose est hyper-facile. Les piles sont incluses dans les télécommandes mais prévoir les piles pour le boîtier. J'ai choisi 2 télécommandes, plus pratique quand on est plusieurs à la maison.
