Conceptually I like this. This is a small, 1 5/8" x 3/8" approximately, device that is used to keep track of your stuff. You install the application on your phone. The setup and connection is quick and easy, it uses Bluetooth. Hold the button on the device and it rings your phone. Press the button on your phone and it sets off a tinny sound from the device. It is a bi-directional divining rod for your gear. If you constantly lose your keys, put the device on your key ring and when they are MIA you trigger it via your phone. This assumes you don't consistently misplace your phone as well. The vendor hope is you buy a bunch of these and attach them to your stuff. A feature that appears to be a bonus is you can turn on the camera from the phone application and trigger the photo with the device. I, frankly am one of those manually anti-dexterous folks who have trouble holding my phone and pressing the shutter. This allows you to trigger the shutter with the FindX device. It also would be good for group shots, prop your phone up and get a larger group.
The device also registers the last time a connection was made and apparently stores that info. So if you have misplaced your tablet and have attached one of these, you can see on your phone via GPS the last place your phone had a connection with the FindX device. You go to that location and trigger bluetooth to find the tablet.
The sum total of directions is a tiny fold out with the device. It says their is a tutorial in the application but it is more like a diagram than a tutorial. I went to their website to see if there was more information there and nope, there wasn't. So good gadget with tepid documentation.
If reviewing a product, it may have been received free of charge. That will NEVER have a bearing on my recommendations.
