Hi there. Just wanted to drop you a line to say a huge thank you for your rat repeller. I’ve had it now for about 6 weeks and gradually the activity in my ceiling has reduced to the point where I have heard nothing for about 10 days now. It may help others to know that my experience was that the offending rodent seemed to take about 3 weeks to begin to “get the message” and I was despairing that I’d have to pay for the usual visits from the rat catcher. But, after speaking with your firm I was encouraged to give it a little longer and sure enough, it would disappear for a few days, then came back but only for about 10 minutes so I assume it just needed another blast and it left. I’m hopeful that it has now gone for good and I’m quite relaxed that if I hear any newcomers they aren’t going to hang around for long. After spending in excess of £100 every time I’ve had a furry visitor this is a fantastic investment – thank you!
