No customer support! In all fairness it did kill two rodents in the 10 days I had it set up but it kept beeping even when there wasn't a rodent inside. We would go outside and check the trap and it would be empty so we would turn it off and on and put it back. After day three of this I looked for contact information on the box or on the instructions but there was none. I spent over an hour trying to find contact information on line but nothing. What I did find were people with the same beeping issue. The general idea is great and it can be an effective kill chamber but before I order a different one I am going to make sure whichever one I order has contact information for customer questions. These people didn't even respond to Amazon's request.
