this is one of two traps that I own from hava hart. I catch large rats in my 1030 and it will get him every time,cause it triggers so easy and fast. I also like the fact that I can open only one door and put bait in a small can under the other door which is solid and acts as a shed to keep bait from getting rained on. its hard to find traps that have solid tops any more,thanks hava hart! I just ordered another 1030 for my cousin. LOOK OUT RATS!
