Query: One GREAT; One a DUD

I bought two traps. One has worked very well and I am very pleased; the other one broke on the second use. The plastic pin that holds the spring in the "set" position broke and I had no alternative but to throw the entire trap away. I was very disappointed because I bought the product after reading the rave reviews on-line. The "plastic entry door" is cute, but I leave it open, the better to encourage the mouse toward the bait. This morning's catch was needlessly cruel--for the mouse. For some reason the spring did not catch him/her on the back/neck, but rather by the feet/tail. The poor creature had gnawed through the plastic covering in a vain attempt to get free and ultimately died from the d-Con poison that I had used for bait.
