Great little device - a bit more little than I expected but it still looks real and the red flashing light completes the illusion.

I had a bit of trouble getting the cover off so I could insert the battery, but when I finally managed it, I realised I was trying to be too clever and it was a lot easier than I thought. I suppose its good to read the instructions before you start!.

I got a short length of electricity cable and attached it to the dummy camera and then fed that through the roof to make it look "live".

In all, I think it does the job well and is very good value.
