content: I purchased this alarm for my pool house/storage shed. I didn't need much. I didn't get much. The alarms are not that loud. The remotes are lucky to work from 25 feet, no where near 100 feet. The system is cheap, made in China. All you have to do is unplug it and turn the switch to off and the alarm shuts off. Takes about 10 seconds and the entire system is rendered useless. My only hope is that if somebody does try to break in they just head for the hills, thinking the system may be reporting somehwere. The loudness of the alarm certainly won't scare them. If they take the time to look at the system, I may find them on the floor, dead from laughter. All in all, a poor system but probably sufficient for my needs. For the price, I shouldn't complain. I wouldn't use it in my house though.
