Review on 🏡 ENEGG Wireless Home Security Driveway Alarm System - Entry Alert, Visitor Doorbell Chime with 2 Plug-in Receivers and 1 PIR Motion Sensor Detector - Quality Sound and LED Indicators - 38 Melodies by Omar Svagera

Can't speak to its weatherproofing as I use it indoors but I have about 3 now. One broke and I had to send it back but there were no problems and the Replacement worked perfectly. One device was installed at a thrift store where we held it over the front door, with one ringer about 30 feet away and the other about a half-block separated by four walls. In both cases, the bells worked well, and the triple batteries in the sensor seemed to last for months without replacement. I think it was almost a year before I had to do it. The second block was housed in a church building that was much smaller. Aside from having to return a defective unit, the replacement worked flawlessly for several months. Now I'm thinking about getting one for my house just as a cheap way to have a security system. There were very few false alerts, and I attribute them to things like leaves and swaying signs that could knock out the laser.
