There are no good description for this product. Does anyone know what they do?

I think this is an ordinary gps modul and description made by someone who does not know there is already a gps receiver built-in in X1.

maybe you use it to help find your keys?

Right but the description confuses me and it does sound exactly like what jabe said. But I would so buy this if it was key finder.

It just a bluetooth GPS module that fits on a key chain. You don't need it as the X1 already has a built in GPS chip. If you had a smartphone without a GPS chip, then there's be some benefit to it.

Or if you wanted to use GPS stuff on a laptop or something with BT etc.

Suppose your X1 is positioned in your car that way that the GPS reception is bad but you cannot relocate it. You can set it up to receive GPS signals from this external module. The module itself can be put anywhere like near a window or on the car's roof or so.

WTF? Did you even read? "The Freedom Keychain GPS 2000 is the world’s lightest and most compact pocket GPS receiver."

It's an external GPS receiver.

gps is receiving only!

you pick up a signal from several satellites and the device calc your position

this keythingy have gps and bluetooth
bluetooth have a range of 10m so even if it could transmit
it's cords to your phone then you would have to be pretty close to the lost keys :P

an external gps, my brother has one but of a different brand. his loads really quick and there's no need to wait on finding satellites. i'm not sure how this performs though, but for a keychain it seems promising for other phones without a built-in gps

I actually have one of those. Well, mine is a white Vodafone branded one, but it's the same chip, hardware, box, everything. It's actually still vaguely useful - it's DGPS capable (WAAS/EGNOS), which the X1's GPS chip is not (augmented accuracy within certain systems, WAAS for North America/Canada and out to sea within several hundred miles, EGNOS for Europe etc), and it has apparently far better reception - my X1i couldn't pick up a GPS signal to save its life inside a BA Boeing 777 flight. The bluetooth'd external reciever picked up and held a strong signal for the entire 3500 mile flight at 40k ft. And inside a plane fuselage, that's got to be borderline faraday cage.
