Well designed and easy to set. Didn't work for me because the moles I have tunnel 8" below the surface which the prongs will not reach. Tried digging out the mound, fill in to the depth of trap capabilities. Didn't work for me.
This mole trap is the easiest to set that I have ever used. I first thought the tines were a little short but after catching three moles with it I decided they were not.
