This trap does the job, but nearly as well as others I have.  THe trap is difficult to set and requires the use of special tools that come with the trap, but are not part of it.  Even with the tools this trap is a pain to set compared to others. Once you get is set and placed on an active run it does the job.  Another issue I have with this trap is that it's design and color make it difficult to see from a disance and impossible to tell if it is sprung.  You have to remeber where you put it and check it periodically.  I recommend poking the tools into the ground next to the trap so you will know where they are.
