Speed Camera Detectors - Inforad K2

[ChrisRad]

I've just bought an Audi A4. It has built-in satnav but doesn't alert me to speed camera. I don't want to use my Tom Tom too for the benefit of speed cameras so am looking for a cheap but worthwhile detector. I've come across the Inforad K2 on Amazon which seems to be too good to be true.

Does anyone have any experience of this device?

Recommended @ £50 compared to the Road Angel at several times the price?

I'm looking for a bargain but don't want to waste my money if the device is no good...
