The camera detector works great, assuming you know how to use it and what you're looking for. It relies on an old trick where camera sensors are generally retroreflectors which always send light directly back to the source (assuming you're within the field of view). Normal reflective surfaces will send the light off at an angle equal to the angle that the light hit it. So as you move around (yes, you have to move around) the flashing light that stays bright regardless of where you are is probably one to check out. Reflections that move or come-and-go depending on your position are probably just shiny surfaces. I was able to easily identify several cameras with this.On the other hand, the RF detector is pretty much useless. Sure, if you were in a perfectly benign RF environment (turned off everything in your house, got your neighbors to do the same, and lived several hundred miles from a commercial broadcast station) it would probably find a transmitter. However, that's probably not where you're most likely to want to use it. For example, in a hotel room where every room around you is going to have a cell phone and any number of WiFi equipment running, this unit will be swamped with the extra "ambient" RF fields. It simply doesn't have enough dynamic range to be effective, and what's worse is that the "attenuation" dial on the side seems to destroy the dynamic range even further. (This is actually a fairly common problem in RF engineering.) Your best bet is to turn the sensitivity all the way until the blue light just stops flashing, and then you might be able to find a strong transmitter if you are right on top of it. (Tried with transmitters at 900MHz, 2.4GHz and 5GHz.) Even in this mode, you would only get a little bit of a change if you were within a few inches. When the attenuation is turned down to where the ambient RF doesn't cause the LEDs to light, even keying up a 1W handheld nearby won't cause any indication on the unit. In the end, I wasn't expecting much for $17 bucks, and I got what I expected. A fun toy, but not as useful as you might think.

The detector works like it should. and was new not used.

So far so good.

mine arrived and the internal rechargeable battery would not hold a charge.

this doesn't work well at all save your money

A lot of pretty lights and noise, functional..doughtful

Crap save the few bucks

Does not work, Returned!
