Seems ok so far, think I’ve tested most features. The long antenna for finding magnets isn’t very sensitive, even when turned up to max. It’s seems like it detects the magnet I’ve tested with only at certain angles, I could be wrong though or maybe the magnet I tested with was weak compared to one used to connect a gps bug to a car. It doesn’t have headphone input but that’s not a huge issue for me, as it has a vibrate mode. Feels nice in the hand, does the job. You can get something similar for cheaper but without magnet detector and not as nice looking and feeling. Next step up from this (software defined radio) is a big price jump, so this will do for now. Happy overall

Fast shipping. The device really works. In the complete set the instruction in English, but on the internet found at Russian (everything is very detailed). Router WiFi clearly determines, the phone reacts when calling and receiving SMS. To find hidden cameras you need to look through the eyes and turn on the red backlight, the cameras will immediately see the glare of the lens. For example, the IP camera is clearly visible, as well as phone cameras. And the eyes of the seals also respond)))

Everything has come. Works on a cell phone if it's in talk mode. Catching waifay. The voice recorder does not determine. Phone if in standby mode will not find. In general, who needs to find a working source GSM that is a good device))))))

Package came damaged (see photos), but contents were OK. Most likely customs opening and checking package. Charged it all night. Have tried it on 2 hidden cameras but no response. To be fair, I need to check I'm using it correctly.

Useful thing. Sensitivity is excellent, the camera shines on hurray, the electromagnetic is also super, but the probe is not very sensitive, the pickup from the guitar saw of course, but I did not buy it In general, solid 5)
