I purchased 3 of these from Amazon. They do work. So far, I have caught 2 moles in my yard and 1 in my neighbor's using the surface technique. One of the traps though has a dangerous manufacturing flaw. The thinner piece of metal on the top of the trap where the trigger bar and safety clip are attached broke on the trap after setting it only twice. I have also observed that over time and constant use the paint wears off this piece and the metal rusts, further weakening it. I have contacted Victor about this problem but have not yet heard back from them. Thankfully Amazon has a very liberal and easy return policy on defective items.
