After I had with special smell beads and Erdvibratoren not succeed to drive my voles, my Supercat vole was recommended. Since I have a large garden, I immediately ordered it three. Inserting and clamping the case is very simple. I especially appreciate that you already can see from a distance whether the tension spring has been triggered. Unfortunately, the voles had always dug in the first three weeks in the case of Earth, so that the traps were just full of earth. Yesterday I got caught my first vole. Judging a clear success this Supercat vole to the total non-success with the smell and the beads Erdvibratoren. The promise that the fishing success sets within a few hours, but could not be maintained. Therefore three star.
