I am very excited about dieesm device. The design is of high quality stainless steel, the mechanism unique and easy to understand the operating instructions and helpful (eg we learn also useful about the lifestyle of the different species of mice (digging, and feeding traces, and duct system), which helps one to catch what you want to catch). In addition, no bait is needed and can be seen on the device, if it has triggered, without having to dig for it.
Only the probing rod, can be purchased as an accessory, I think this is not bought, but used an existing bar and to smooth the transition uses a bent spoon, for this purpose unnecessary (I got him, the probing rod at the other end that is a ball ). So if you want to save, should do in the probing rod, the punch and of course TOPCAT themselves are very well spent, even if it only appears very expensive - I wish I had tried this device much frühre!
