I hid 4 cameras in the room and tested it with this gadget, it found all of them. I also tested the wireless network interference function, and it really made my 2.4G network unusable, and it had no effect on the 5G WiFi signal. We are very satisfied with it.

If you want peace of mind for yourself and/or your family, this product is IDEAL for you. Use at home, business, traveling, etc. It is an exceptionally powerful personal privacy tool!

Ease of Use – excellent
Instructions – excellent
Compact size – excellent
Price – Outstanding Value

The detector is simple to use. Scan a room to detect hidden cameras, listening devices, and block the signals for those unwanted devices!

I have tested it at home on my routers, security cameras, and webcams, ALL worked well!

The compact and portable design makes it convenient to carry as well.

Its rechargeable feature is also convenient.

Overall, the detector is a tool for anyone who values their privacy. I have been looking for a powerful detector tool and I finally found it with this device. Compared with other detector tools, it offers exceptional value without compromising quality. I highly recommend this product.

Bought it for the wireless blocking feature and I got this to check out area's around my vacation property.
I tested it on my own cameras to get a feel for it and then walked around. I like the silent ability and its battery life is decent.
For the price you cant go wrong.

I use this for monitoring small spaces in our smoke duct and between floors. Should do a little bumper around the camera to protect it from heavy use
Quality seems good but I've only had it a few days.

I purchased this CO2 monitor mainly because of its compatibility with the Tuya app, which I already use to control my smart light bulbs and smoke alarms. The ability to connect all my smart devices together and set up a link that automatically triggers my smoke alarms in case of dangerous CO2 levels is fantastic.

Regarding privacy, I can only speak for the iOs version, and Tuya did request access to my location, local network, Bluetooth, and Homekit. However, I don't feel this is anything unusual. The location permission was only requested when I tried setting up a home/away routine, which I think is a reasonable tradeoff for the convenience this smart device provides. Overall, I'm happy with my purchase.

This monitor does what it’s supposed to do. I did test with with and smoke and it alarmed right away. Have it installed in our basement to detect any harmful gases. So far hasn’t alarmed or detected any gases which is great. Nice to know air quality.

This is nice. Although I am not interested in the amount of humidity, I am interested in a Carbon Monoxide and Smoke Detector for our Airstream. We checked it out with the smoke and works and if the carbon monoxide alarm is as loud it will be great. It has a nice clear design and it is pleasing to look at.

I like how this is more modern than the traditional ones that hang on the wall and look like a smoke detector. This has a digital read out. Mine says all zeros, I assume it is accurate as I have a hand held unit also - that isn't going off. This was simple to turn on and charge. Does NOT come with a plug for the charging cable, only the cord that goes into a USB port.
