I of this trap since numerous years. I have even two. they catch all the mice who cross their path. 2 instructions must always be followed: 1- choose the bait: the ideal is a chocolate biscuit type "Prince". The negative comments about this trap must come from people who put cheese. You will put all fat and mice will actually miss. Like what, the reality does not always reach cartoons. 2- if you ask some share this trap should be checked EVERY DAY. Otherwise, it will turn into a very cruel purpose, which is to put its objective. And so, no mouse has ever destroyed me. This trap is perfect and infinitely better than a fag. Why kill mice when we have free alternatives that work just as well. Thank you for your appreciation if you liked that comment and not unnecessarily kill the mouse ... ............ Adding to comment from December 2014: Attention to the price! I saw this comment from the price almost doubled! DO NOT BUY THIS PRODUCT OVER 7 SHIPPING INCLUDED. Sometimes it is better boycotting the junket for the product not to encourage a practice of abusive prices. This product should return to offer "Cart more" unless 7. Do not exaggerate, it is a plastic box. By cons, 6-7 including shipping, please. ---------------- Updated December 21, 2014: Amazon returned to price 6.39 including postage. Amazon thank you. Really, it's not for nothing they are the best of the Internet sellers. Amazon has the intelligence to listen to its customers. So, we are their faithful. They all included. Good shopping on Amazon.
