This works so well for our window well cover. It adds an extra layer of security, was easy to install and the adhesive is strong. Alarm is very loud. Good value for the money.

I mounted this on the inside of my shed door for added security. This alarm has a few different options and loudness, it works great and it's loud. I also like that the remote works thru a steel door. It's not all fancy or techy but it works perfectly.

Very satisfied that I purchase this product. It appears to be doing the job. The noise is very loud. The sound level is very high and good. So far so good I'll keep you guys posted. But yeah if anybody's looking for some kind of security alarm system that's affordable. I would definitely recommend this as it says what it does. And you just have to have that patience in setting it up. The information is easy on how to install. I did not use their tech support so I don't have a comment on that. But this is a very good and affordable product as it says what its going to do therefore i would recommend it.

The first one I purchased did not last an entire summer. I messaged the company and never heard back. The second one I ordered came used. The battery was used and beeping when I took it out of the box. Wish the company would let me know if this is normal for their products.

This will clear a room or your front porch in a hurry..... I use this as a second level deterrent for uninvited solicitors who ignore and defy my overwhelmingly clear signage and decide to ring my door bell anyway.One quick press of the remote and WOW!!!!! They can't stay on the porch and they generally leave pissed off. They should have respected our wishes and hopefully they will think twice about proceeding forward when people clearly mark they do not want any type of solicitors.

I bought it for the chime mode because I just want a 1 time chime when the gates opens/closes but when the sensor is triggered, the 'chime' goes on for 30 seconds. I thought maybe my unit was defective but after reading the manual, found out it's by design. So if you want to hear the 'chime' for 30 seconds after every time the gate opens, get this. Otherwise my search continues, why is it so hard to find a waterproof, outdoor gate alarm that chimes just once?

Update: the company contacted me and sent new alarms for my grandparents. The new ones work great! The company was also very on top of things and helpful.I bought a set of these for myself and then another set for my grandparents. While they have worked for me, they have given my grandparents all sorts of issues. They go off randomly when they’re untouched and lined up correctly. They have been going off recently after being taken down and turned off. My grandpa finally had to just take the batteries out.

Although ok, improvement to the rear fastener that holds unit to mounting surface could be improved.
