Motorola Scout- does anyone have one?

[Notthecarwashagain]

I've just noticed that Argos are selling the Motorola scout half price at the moment, making it in budget for DDs Christmas present.
She misses her dog whenever she's out, and although I'm pretty sure the dog does nothing but lie around on the sofa putting her fur all over my space I think DD would love to be able to keep an eye on her!

Does anyone have one? Is it useful or just a bit gimmicky?

Thanks in advance!
