This trap is is strongly built with a very powerful spring. Setting it can be intimidating because it requires strength and care because one could easily break one's finger or even a wrist. I've tried setting it and found it too difficult. Because of the strong spring, releasing a caught rodent for disposal after being trapped, would be a huge, messy challenge in reverse. However, inertia on my part has prevented me from requesting a refund even though its unlikely that I will put it to use. My rating is not for use of the product, but for safety concerns. I would like to hear from users who have successfully used this trap on a continuing basis: set trap-catch- release and dispose-and reset.
