We're very disappointed in this product.  We have a mouse infestation and the HaveAHeart traps are the only ones we find that work successfully on a regular basis.  This Victor trap for some reason is not working.  We make sure we secure the lid really well (they got out the first time when we evidently did not have it tight enough).  Some how, they were getting in, removing the peanut butter/choc. chip delight and leaving.  So with this trap we have been housing and feeding these ingenious little critters.  We have to quit using this device since it just isn't working and we can't figure out exactly why.  We are terribly terribly disappointed because although the HaveAHeart traps are excellent, they only trap one mouse at a time.  Which means with an infestation, you are losing the battle - fast!!
