LZHZJOY Portable Anti-Spy Detector - Wireless Camera Finder, Audio/GPS Signal Detector for Hidden Bugs & RF Signals | Home Security, Office Privacy & Travel Protection

This is a good and helpful signal jammer to detect hidden cameras, microphones, or other bugs. We tested it out and it left nothing undetected that we knew was there. When on the highest range it was over-detecting things in our house in every direction, so definitely fiddle with the settings. I had to re-read the directions several times to figure out exactly how to use it correctly and get the best readings. I tested the laser mode and it works great. We also used this to test the working power of some faraday fabric I ordered. I would say this is a very helpful device! super techy stuff.This detector is easy to use and very effective at detecting various different kinds of surveillance devices. It gives my wife a secure feeling while traveling and staying at different hotels and using strange restroom facilities. I recommend highly!Very easy to use and highly portable.It does a good job of finding cell phone and Internet signals.Because it's compact, I can carry it around with me, and it's very sensitive.I was a bit skeptical at first....I followed the instructions and BAM! Within 7 minutes I located the GPS.Its Great!Due to my work, I often go on business trips to hotels. I have seen many places to choose this one. The appearance of this pen is very suitable for carrying, and its sensitivity is really strong.Too many hotels now have tiny camera monitors. Buy one to protect your privacy. It's very convenient to use.When on full band it gives false readings. Didn't work for me at all.I did not understand this gadget function. I will not recommend it
