BTFDREEMRF Wireless Signal Scanner for Home Office Travel， Even if it is Used continuously for 4 Hours,Built-in 400 mAh Rechargeable Lithium Battery,

These are Christmas gifts and I think my family will love it.

Really didn't like this device. Held it near my iPhone camera. Nothing. Held it directly in front of my iPhone camera, and it took 10 full seconds to even detect it. How are you supposed to do a fast sweep when you need to hold it for so long at the exact camera spot to even detect it?We have security cameras in our home and it didn't even detect those because they are wired and not wireless. Useless.Was very disappointed with this product.

Can someone, in easy terms, explain how this works and what to look for. Sorry but I’m so confused. The instructions are very vague, saying what might happen, but not what I’m supposed to be looking for.Thank you!

I bought this over a month ago, and it worked really well. A couple of days though it has started to alert to RF at full strength everywhere I go. Maybe don’t keep it in your pocket every day and it will work great.

I bought this more as a joke, but it sure works. I will take it to my future hotel stays to be safe.

Does it really work? Not sure cause everything electrical around the house triggers it. What use is that? This is more of a gimmick and misguided if you're truly trying to fine spying devices. You have better luck just looking around the house with your own eyes.

This item was purchased ahead of time for a trip. While on the trip I realized it would not hold a charge and could not even use it. When I returned home, it was past the return date so now I am stuck with a defective item. Very disappointed!!

The product seems to work great so far. I commented to the seller that the unit was defective after a month. However, I forgot that you would need to push and hold the on/off button for a few seconds to turn it on. It’s now working perfectly again. Great product. Recommended.
