"Had a major mouse infestation (we were at the point where upon just walking into the kitchen I saw 4 mice in quick succession!) The house next door has put down poison and we bought 8 of these plug-ins (for a 4 bed house). Since having these plugged in i havent seen any mice or droppings. Once plugged in they make a very quiet clicking noise about once every 5 seconds - no louder than a ticking clock. I paid £24 for 8 (+p&p) -- much cheaper than buying from the high street and well worth it!!!"
