Meanwhile, I have already had multiple success. A major problem is the hole maker. The should be discarded. It works best if you aufgräbt the aisle with a small shovel. The hole may like to have 20 cm diameter. Then the trap set close to one side of the aisle. Links and the trap clog right column with soil or grass clippings. Then etc. the dug hole from above with a patch of grass cover tightly.
Handling the case does not seem to bother. In an active transition the case should trigger within 1-12 hours. Otherwise, you are looking at a different location. It is important to choose a place where you can set up the trap is good. It is also important, the bottom of the hole and the transition but firmly (best hand) - there must be no loose earth exist. Perhaps that's why the hole Stecher works poorly, since crumbly earth you create too much loose material and is not good for hard rankommt Press.
Meanwhile, both lower arms are broken. The stability of the device is therefore not well - more suitable for casual users. Meanwhile, I bought the Topcat case made of stainless steel. Although more expensive, but much more stable and also very good catch quota.
