Thankfully in the time they have been down we have not caught a mouse (the culprit of the droppings has disappeared!)
However, I would 100% buy these again as a better alternative than poison / killing traps. They are a good size for a mouse as I was worried about trapping a tail but these are longer than other products. A nice humane alternative to catching the rodents.
Great value for money and easy to set up (no set up required)
