Delivery a bit long, but it was two weeks expected. At first I doubted the effectiveness of the trap, but after a week of using a mouse was taken. The trap is fairly thick plastic (important because the mice nibble a bit of everything, including plastic mechanism and the trap becomes unusable. This is not the case for this one). The hatch is easy to arm, the door closes slowly but surely on the mouse, so without hurting her. The mouse is captured alive by a bait made of bread. In the morning she was released in the opposite fields.
