Mengshen Wireless Door Alarm, Anti Theft Burglar Alarm, DIY Protection Ideal for Home, Garage, Apartment and RV (Include 2 Alarm 1 Remote Control)

Im sure the instructions may have been very well written in the language it was written in, but not when it was converted very badly to english. I cant figure out if I can adjust the volume or not, but I would rather not annoy my neighbor's when there isn't someone breaking in. Just get a person to translate them better because it seems like a good product, I think.

Very easy to install. Definitely loud enough to hear anywhere in our home.We got this because my 4 year old was letting herself out of the house. Either early in the morning or when I was attending to another child.This is a LOUD easy to install device and it does the job. The remote is handy for arming and disarming.Only issue ii have found is due to our humid area the mounting tape has not held up. Less than a year and we have had to remount

It does what it’s meant to do. The key remote is awesome thing and the sound level of the alarm itself is amazing to scare the living heck out of someone trying to break into your house or apartment.The cons and the reason why I gave it a -1star is because arming the alarm itself is so loud that it becomes a pain when trying to arm it at different times and not trying to disturb my neighbors or guest. If there’s a way to fix that, that’ll be awesome.

I couldn't figure out the motion alarm but the device is loud and intimidating. I bought a second fob for the other device I couldn't get it to connect. I'll try the instructions on Amazon website.

Cumple su función, es mejor comprar la que viene con alerta de vibración

Not sure if this will do what I intended seems little small and not sure if it will deter breakins

Had someone try to break in my garage door. Was looking for an alarm to prevent this from happening again. This item works great used it on my garage door. The alarm remote is the best part i just have to disarm the alarm before entering. If the alarm is not disarmed it sets off a loud alarm sound.

Really works great no cmplaints here

Good product does what it is supposed to due but major design flaw if your using for a inexpensive security alarm. Standard install the alarm it self needs to be mounted in the door frame making it very easy for a would be burglar to "disarm". I opened the unit, un soldered the sensor (1of2 in the unit) and extended the location to relocate the alarm to a area where it can't be accessed by a would be burglar easly. It was pretty easy to do and makes the unit much harder to "disarm". In the photo the blue tube with the wire is now the sensor to attach to the door frame.

Very accurate sensor.

This devise is absolutely brilliant, I purchased for my static Caravan, it’s got a small remote on fob very loud when activated, brilliant when we stay there it’s nice to feel safe when sleeping, or when we leave there, it flashes when on would highly recommend if you want something on your door for peace of mind when your not at home.

Easy to install, value for money sbd gives additional peace of mind. Gave just ordered another.

Brilliant. I've had others but none as LOUD and with a working fob. I've now got 2 of these for my home and I'm planning on purchasing 2 more for the static 2 door caravan. IDEAL
