## Customer Reviews

### ⭐⭐⭐⭐⭐ Five Stars
*by A***R on 31 May 2016*

So far so good no more sighting of rat !.

### ⭐⭐⭐ Way overpriced!
*by M***W on 30 June 2015*

Have not fitted yet so will comment later but I will say that someone somewhere is making an a lot of money out of this! I challenge anyone to say this is not overpriced by at least £60! Looks like it should cost no more than £20! If it works most will forgive the price I suppose.
