It would be illegal in the UK as transmitting Radio frequencies requires a licence that you just wont get!

However, assuming it does what it says it will protect you from K band Gatsos & Laser guns and you'll get loads of X & Ka band false allerts.

It will not protect you from Ku band mini Gatsos, Truvello front facing cameras(triggered by induction loops) and of couse VASCAR.

 

 

I think I read somewhere that the police lasers can tell if they are being jammed - guaranteed to get you pulled!

 

These things don't work very well in the U.S, and I don't think they will fair any better where you guys are.
A friend of mine has one of these things and has gotten 2 speeding tickets while using it.
