Review on π KERUI Wireless Entryway Protection Transmitter by William Bell
Great for cats - USB powered recommended
I bought this mainly to warn when a cat was at the door. It also notifies me when one of my packages has been delivered to my doorstep. It was outside/outside (in a plastic bag) and it survived. The batteries in the receiver ran out pretty quickly. Although the receiver still had battery power, it did not "ring" when the detector was turned off. I removed the batteries and now power it via USB with a RevainBasics 3-Output Surge Protector with 2 USB ports. It works great and the sound is louder than new/fresh batteries.
- Very good value for money
- Incredible piggy bank
