I have a strong background in electronics and data communications. Professionally I am an IT Security Architect. I shop Edmund's Scientifics frequently and buy quite a few items as a hobby. Recently, I bought three RFID items; two besides this one, are also reviewed.
This is the best and least expensive product. It works very well and actually allows you to find a lost item. As you get closer to the items the blinking white LED blinks faster and the beeping increases in frequency. This items works as advertised and is worth buying if you ever lose your keys, mobile phone, or other items.
